Frequent problems

Plantar fasciitis: causes, symptoms and treatments

Plantar fasciitis is a common foot condition. A strain or break in the plantar fascia, the fibrous band that supports the arch of the foot, is at the root of this condition.

Heel discomfort is the most prominent sign of this condition. It will be felt from the first steps in the morning or after a lengthy period of sitting.

You can find plantar fasciitis symptoms, causes, and remedies are listed below.

A person with plantar fasciitis will feel discomfort when they first walk in the morning, but it will subside over the day. They will also experience discomfort after sitting for an extended period of time.

Plantar fasciitis can also cause the following symptoms:

  • Pain when palpating your arch or when pressing on your heel;
  • Standing or walking causes pain, which might worsen over time;
  • Tension on the outside of the foot, which can cause compensating foot and leg discomfort;
  • A condition...

Foot bunion (hallux valgus)

Is it difficult to walk on your foot because of a deformity in the big toe area? Is your big toe extending from the base due to the same deformity? Do you have pain and inflammation in your joints?

If this is the case, consult a podiatrist right away because you most likely have a bunion (hallux valgus).

Don't be deceived if the bunion appears to be painless at first.

Hallux valgus can produce a variety of unpleasant symptoms, ranging from minor aches and pains to ingrown toenails and mobility issues.

Here's a rundown of the signs and symptoms of a bunion:

  • The appearance of a hump at the base of the big toe caused by a common joint displacement
  • Beginning of the displacement of the big toe towards the 2nd toe
  • Appearance of joint stiffness and pain when moving straight
  • Having trouble putting on shoes (widening of the forefoot)
  • Second toe deforms and becomes clawed or...


Do you ever get a pain in the foot that makes you feel like you have needles or pebbles in your shoes? If so, you may have metatarsalgia.

This is what we call the pain in the area of ​​the foot sole, between the arch of the foot and the toes. If you have metatarsalgia, you may experience pain in a very localized area or on your entire forefoot.

Metatarsalgia is basically caused by inflammation. Often, the patient who suffers will feel that their socks are always bunched up at the base of the toes. Sometimes they will even feel like they are walking with a pebble or needles in their shoe.

  • Burning sensation at the front of the foot
  • Swelling of the front part of the foot
  • Swelling on the front and top of feet
  • Calluses on the front part of the feet
  • Difficulty crouching down on bent toes
  • Twinge in the foot phalanges

Metatarsalgia can be caused by a number...

Morton’s neuroma

Do you suffer from foot pain that resembles electric shocks in the forefoot, followed by numbness in your toes? If you experience this, it can be symptoms caused by neuroma, also known as Morton’s neuroma.

This problem is due to a thickening of the nerves located between the toes, as a result of compression or friction. This leads to inflammation, numbness, burning or a sensation of small electrical discharges felt in the toes.

Although there is no outward sign of this condition, neuroma triggers several uncomfortable sensations in different areas of the foot.

  • Numbness and tingling in your toes
  • Sensation of burning in the forefoot
  • Sensation of having a bunched up sock under your toes
  • Sensation of small electrical shocks in your toes
  • Toe cramps

These symptoms are aggravated if you remain standing for long periods of time or if you wear narrow shoes that are not...

Ingrown toenail (onychocryptosis)

Ingrown toenails are a frequent nail issue that can be extremely painful and even incapacitating. It's identified by a toenail that grows into the flesh and punctures it.

Ingrown toenails cause irritation and, in the worst-case scenario, infection, resulting in painful toes.

As a result, it is critical to address the problem as soon as possible in order to prevent the situation from spiralling out of control.

Let's look at the causes, symptoms, and remedies for ingrown toenails.

An ingrown toenail can be identified by a variety of symptoms. Inflammatory redness, pain when squeezed, and, in some circumstances, blood or pus on the side of your nail are all possible symptoms.

However, keep in mind that an ingrown toenail has three stages;

  • First stage: there is a small inflammation and pain when pressed.
  • Second stage: we observe an infection and the wound becomes more visible.
  • Third stage:...

Plantar warts: causes, symptoms and treatment

A viral infection is what causes a plantar wart, which is a skin lesion. It can either stay dormant for years or develop and spread quickly. It's a contagious skin condition that affects you and those around you.

The HPV, or human papillomavirus, creates these lesions. Despite the fact that it is a harmless virus, it is recommended that you get treatment as soon as possible to get rid of it.

The plantar wart frequently appears as a tiny, rough, spherical, and flat lump. It will manifest itself in a variety of ways.

  • Appearance: it consists of spongy, brownish or yellowish tissue with small black dots;
  • Size: it can measure from a few millimeters to several centimeters in diameter;
  • Pain: plantar warts can be painful, even though they are uncommon. Friction or a pressure point can produce this type of pain, which can become severe;
  • Posture problem: the foot pain caused by the plantar wart can lead to a foot positioning...

Nail fungus (Onychomycosis)

If you suffer from a nail infection like nail fungus (onychomycosis), don’t let this problem go untreated. Most often affecting the big toe, it is a fungal infection that causes pain and that is very difficult to treat.

However, if you take the time, it is possible to get rid of it. Read on for further information on nail fungus.

Onychomycosis is a fungal infection, that is, caused by fungi. It causes different symptoms in the affected individual. The main symptoms associated with this podiatric problem include:

  • Nail discoloration (it becomes white, yellow or brown)
  • Nail that grows thicker, curls up or changes shape
  • Nail that breaks more easily
  • Painful, infected nail
  • Residue under the nail

As mentioned below, it is very difficult to rid oneself of an infection like onychomycosis. So, as recommended by podiatrists, if you suffer from any of these symptoms, do not...

Corns, calluses and severe corns

Corns, calluses and severe corns are formations of dead flesh under the feet. They can be embarrassing for people when they walk or exercise.

Often, people with delicate feet tend to suffer more. However, this foot problem is easily treated.

It is common for an individual to develop skin problems. However, it is important to know the difference between the 3 pathologies described below.

  • Corn: this is a localized area of skin that thickens a lot. When a cluster forms, it bores into the skin and causes pain similar to that of a pebble in a shoe.
  • Callus: a corn has several names, like callosity or hyperkeratosis. It is characterized by an accumulation of excessive layers of skin and can form cracks in the heel if not treated.
  • Severe corn: these are also corns, but in their case, they are more advanced. They are painful, with a brownish center. They develop because of excessive pressure on the skin that has...

Heel spur (Lenoir’s thorn)

When you place your foot on the ground, do you feel discomfort beneath your heel?

Seeing as calcification under the calcaneus is quite common, Lenoir's thorn might be the disease that affects you.

The heel spur, known as Lenoir's thorn, is a bony protrusion on the inside of your heel. This anatomical structure can be seen by X-ray.

People with this condition frequently experience pain in their heels while taking their first steps in the morning or after sitting for a long period. They may also notice a painful spot in their heel, such as a spur.

Imaging is usually used to detect this structure. It is very difficult to feel by touch.

Let's take a look at what makes heel spurs develop, as well as the therapies that can help you get rid of the discomfort they produce.

Heel spurs usually do not cause any symptoms.

When walking or standing for lengthy periods of time, the majority of persons with this...

Diabetic foot

Diabetic foot develops as a result of the neuropathy that comes with poorly managed diabetes. When blood sugar levels are excessively high for an extended length of time, it impairs a person's neurological system.

The injury results in a lack of sensation in the lower limbs, among other things. Peripheral neuropathy is the medical term for this condition.

Blood vessel constriction is also caused by poorly managed blood sugar levels. Wounds and ulcers form more easily and heal more slowly as a result of inadequate circulation.

If left untreated, these two factors explain the dangers of a diabetic foot. A diabetic foot sufferer may have trouble recognizing a wound or a temperature change. As a result, individuals may be unable to discern between discomfort that requires the attention of a podiatrist or other health care provider.

Diabetic foot is a severe disease that can lead to gangrene and, in the worst-case scenario, amputation. That's...

A podiatrist’s treatment for plantar warts

Plantar warts are common skin lesions that can be quite unsightly. They are often harmless, although they can be infectious and unpleasant.

In reality, these growths on the foot might cause bleeding or create other issues such as irritation, pain, or infectious cellulitis in the long run.

Furthermore, if you are diabetic, elderly, or immunosuppressed, your plantar warts are more likely to cause problems.

Fortunately, plantar warts may be treated in a variety of ways to reduce the risk of infection and consequences. Let's have a look at those.

Your podiatrist can write you a prescription for painless wart treatment at home. The majority of these medicines are used topically.

Prescription medication care can:

Ingrown toenail treatment by a podiatrist

An ingrown toenail (onychocryptosis) is an inflammation caused by a portion of a nail (usually on the big toe) penetrating the surrounding skin.

While usually minor, it is nonetheless a common nail problem that can result in pain and inconvenience in your daily life. If the ingrown toenail is not treated, it may lead to inflammation and exacerbate the pain in the foot.

Do not worry, however, as there are a variety of useful therapies available to help you get rid of ingrown toenails and get your feet back on track. Learn more in this article. 

Medical nail clipping is one of the most traditional nail care procedures. Nail clipping is a common solution for ingrown toenail problems that is performed by a podiatrist or a specialized nurse (assistant). Professionals in the field of foot care can customize a cut to your nail's condition.

Nail care, on the other hand, is more than simple nail trimming, as antibiotic creams or baths can...

Nail culture

Nail culture consists of taking nail and skin fragments from under a nail that appears to be affected by a fungus.

The main purpose of this procedure is to rule out a diagnosis of various pathologies comparable to fungal toenail disease. 

Examples include eczema or psoriasis, which may have similar symptoms but do not require the same treatment as onychomycosis.

Minimally invasive, nail culture has many benefits. 

One of these is to facilitate the detection of a fungal foot infection that is difficult to treat if not treated early.

Learn how nail culture fits into the podiatrist's arsenal of diagnostic tools and how it can help in selecting the right treatment for you.

Some symptoms of nail fungus are similar to other skin infections such as  psoriasis and eczema when left untreated. 

The following symptoms are similar to those of nail fungus and are sometimes observed in patients with...

Thick and malformed toenails

Toenails that become thick, hardened, misshapen, or even yellowed as a result of moisture or traumatic injury can affect anyone.

To help with this type of inconvenience, several treatment options are available to the patient.

If you're dealing with deformed nails, dystrophy, or onycholysis, podiatrists will help you get to the root of the issue.

Let's look into some of the treatment choices for thick, misshapen nails.

The term "toenail deformity" refers to a change in the shape of the toenails as a result of trauma or infection.

Toenail dystrophy, on the other hand, has to do with texture changes.

The deformations of the toenails are caused by a variety of factors.

We may consider, for example:

  • Fungal infections, like nail fungus
  • Trauma of the nail plate, by crushing or cutting
  • Shock trauma to the nail matrix
  • Poor healing after shock
  • Fractures or infections...

Treatments for paronychia of the toe

Much like the ingrown nail, paronychia involves inflammation or infection of the cuticle of a toenail.

The inflammation of the skin around the affected nail is often caused by the bacterium Candida albicans (candidiasis thrush).

This results in a throbbing pain, redness and swelling of the affected toe.

If left untreated, this condition can eventually lead to pus accumulation and infection that spreads further to the toe or even the foot.

Learn more about the medical treatments for paronychia available at podiatry clinics.

As mentioned earlier, when the foot contacts a candidiasis-like bacteria, it can develop an infection of the cuticle.

As a result, this infection can lead to the accumulation of pus under the top layer of skin.

In this case, the podiatrist may suggest treating the purulent area with drainage.

Usually drainage of the subungual abscess happens as follows:

  • The...
  • Treatment for excessive foot sweating

    Excessive sweating is a symptom of hyperhidrosis, a medical disorder that affects the sweat glands.

    The soles of the feet have a high concentration of these glands, therefore they are more likely to be impacted by excessive perspiration.

    Although there are various home therapies for hyperhidrosis, a more serious problem will almost certainly necessitate expert help.

    Let's look at some of the treatment options for dealing with excessive foot sweating.

    Electrotherapy and its influence on excessive sweat secretion are at the heart of iontophoresis's mechanism of action.

    A typical iontophoresis foot treatment session goes like this:

  • The patient is asked to sit in a chair barefoot.
  • The feet are immersed in a water-filled therapy tub.
  • A control device sends a very mild electric current into the basin.
  • An iontophoresis session typically lasts 20 to 30 minutes.
