Tendons are fibrous tissues that connect muscles with bone. The Achilles tendon is the largest tendon in the body. It connects the calf muscles at the back of the leg with the heel, and facilitates movements such as jumping, running, and walking. 

Because the Achilles tendon is engaged so frequently and bears a great deal of pressure and stress throughout the day, it can become injured. Achilles tendon injuries cause the tissue to become irritated, inflamed, and swollen. Pain can come on gradually or be immediate, and will vary from mild to severe depending upon the injury. Where the pain occurs will vary as well, from just above the heel up through the back of the leg. There may also be stiffness in the tendon.

Achilles tendon injuries can often be caused by repetitive stress. They may also occur while running, playing tennis, gymnastics, football, basketball, dancing, soccer, baseball or other sports that require speeding up, slowing down, or pivoting quickly. Wearing high heels, falling from an elevation, stepping in a hole, having flat feet, bone spurs, tight leg muscles or tendons, wearing improper athletic shoes, exercising on uneven surfaces, or starting a new type of exercise can also cause Achilles tendon injuries.

The two most common Achilles tendon injuries are tendonitis and ruptures. Tendonitis causes painful inflammation and can occur in different parts of the tendon. Non-insertional Achilles tendonitis occurs when the fibers in middle of the tendon begin to break down, thicken, and swell. This condition typically affects younger, more active adults. Insertional Achilles tendonitis occurs where the tendon inserts into the heel bone. It is common for bone spurs to form with this type of injury. This condition can affect people of any age and level of activity.

Achilles tendon ruptures are a tear in the tendon. These breaks may be partial or complete. There may be an audible popping noise at the moment of injury and the pain will be sudden and severe.

An Achilles tendon injury can be diagnosed by your podiatrist after they examine you, check your range of motion, and possibly perform a calf squeeze test or review an X-ray or MRI. Depending on the type and severity of your injury, your podiatrist may treat your condition with rest/ice/compression/elevation (RICE), nonsteroidal anti-inflammatory medications, heel lifts, and stretching and strengthening exercises. If you have torn your Achilles tendon, treatment may include physical therapy, ultrasound, shockwave therapy, or possibly even surgery.

Fungal infection of the toenail, or onychomycosis, typically appears as a gradual change in a toenail’s texture and color that involves brittleness and darkening.  The fungal infection itself occurs beneath the surface of the nail.  Aside from discoloration, other symptoms include the collection of debris beneath the nail plate, white marks on the nail plate, and a foul odor emanating from the nail.  If ignored, the infection can spread into other nails and the skin; in severe cases, it can hinder one’s ability to work or walk. 

The toenails are particularly vulnerable to contracting infection in moist environments where people are likely to be walking barefoot, such as around swimming pools, public showers, and locker rooms.  Fungal infection may also be more likely to occur in nail beds that have been injured, and sufferers of chronic diseases such as diabetes, circulatory problems, or immunodeficiency conditions are particularly prone to developing fungal nails. 

Fungal nails can be primarily prevented by practicing proper hygiene and regularly examining the feet and toes.  Carefully washing the feet with soap and water and thoroughly drying the feet afterwards are essential.  Other tips include wearing shower shoes in public areas, changing shoes and socks daily, keeping toenails clipped at a short length, wearing breathable shoes that fit properly, wearing moisture-wicking socks, and disinfecting home pedicure tools and instruments used to cut nails.

Fungal nail treatment may vary between patients and the severity of the condition.  Your podiatrist may suggest a daily routine of cleansing that spans over a period of time to ease mild infections.  Over-the-counter or prescription antifungal agents may also be prescribed, including topical and/or oral medications.  Debridement, or the removal of diseased nail matter and debris, may also be performed.  In more severe cases, surgical treatment may be needed.  In some instances, the temporary removal of the fungal nail allows for the direct application of a topical antifungal to the nail bed.  In other cases, a chronically painful fungal nail that has not responded to other treatments may be permanently removed; this allows the infection to be cured and avoids the growth of a deformed nail.  

Hammertoe is a foot deformity that occurs due to an imbalance in the tendons, muscles, or ligaments that are responsible for holding the toes in their normal position. This condition may be caused by poor footwear, foot structure, trauma, and disease. The most common solution for hammertoe is to relieve the pain by changing your footwear and wearing orthotics. In severe cases, surgery may be required.

The shoes that are most likely to cause hammertoe are high heeled shoes or shoes that are too tight in the toe box. Tight shoes will force your toes to crowd together in a curled position. This position will likely continue when you take your shoes off. Another cause is trauma. When you stub your toe, you are increasing the chance that you will develop hammertoe.

There are risk factors that may make you more likely to develop this condition. Women are more likely to have the condition compared to men, and it is also more likely to appear in those who are older in age.

Many different foot problems can be avoided by wearing shoes that have adjustability, adequate toe room, and low heels. Furthermore, if you want to buy new shoes, you should look to purchase them at the end of the day and make sure you know your correct size. The importance of buying shoes at the end of the day is that your feet swell as the day progresses. You should also ensure that you are wearing your correct size because your shoe size may change as you grow older.

To diagnose someone with hammertoe, your podiatrist will need to conduct a thorough examination of your foot. Your doctor may even order an x-ray to evaluate the bones and joints of your feet and toes.

If you have hammertoe, your podiatrist may recommend that you wear shoes that fit you better along with inserts to place inside them. Additionally, he or she may suggest special exercises for you to perform to stretch your toes. One helpful exercise it to pick up marbles with your feet or crumple a towel with your toes.

Prior to meeting with your podiatrist, it will be helpful to make a list of all the symptoms you are experiencing. You should also make a note of medications you are taking and important personal information about your medical history.

Flatfoot is classified as having the entire sole of the foot in contact or near contact to the ground while standing. The disorder is also known as fallen arches, because those affected have no arch in their feet. Flexible flatfoot and rigid flatfoot are the two types of flatfoot.

A person has flexible flatfoot if when sitting or standing on their toes, they have an arch that disappears when they stand with the entire foot on the ground. Flexible flatfoot may also be called “pediatric flatfoot” because the condition first appears in childhood. It is common among infants because the arch does not develop until the age of 5 or 6 years. Rigid flatfoot is not as common in children as it is with adults. This type of flatfoot is developed due to the weakening of tibialis posterior muscle tendon, a major supporting structure of the foot arch. Development of this deformity is progressive and shows early signs of pain and swelling that begins at the inside arch of the foot and moves to the outside of the foot below the ankle. More severe cases can possibly lead to arthritis of the foot and ankle joints.

Although most cases of flatfoot involve people born with the condition, some less common causes are obesity, diabetes, pregnancy, and osteoporosis. In some cases, flatfoot may come with no symptoms at all and does not require any type of treatment. With other cases though, symptoms may include pain in the shin, knee, hips and lower back. If a person with flatfeet experiences such symptoms, a health care provider may suggest using orthotic devices or arch supports, which may reduce the pain. Wearing supportive shoes can also prove more comfortable with flatfeet and staying away from shoes with little support such as sandals. Other methods to relieve pain also include stretching the Achilles tendon properly and using proper form when doing any physical activity. In addition, losing weight can reduce the stress on your feet and reduce the pain.

Heel pain can be difficult to deal with, especially if you do not know what the underlying cause is. If you ignore your heel pain, the pain can magnify and potentially develop into a chronic condition. Depending on the location of your heel pain, you have developed a specific condition.  

One condition is plantar fasciitis.  Plantar fasciitis is caused by the inflammation of the plantar fascia, or the band of tissue that connects the heel bone to the base of the toes. The pain from this condition is initially mild but can intensify as more steps are taken when you wake up in the morning. To treat this condition, medication will likely be necessary. Plantar fasciitis is often associated with heel spurs; both require rest and special stretching exercises.

There are various options your podiatrist may suggest for heel pain.  Treatment options for heel pain typically include non-steroidal anti-inflammatory drugs (NSAIDS), which may reduce swelling and pain. Other options are physical therapy, athletic taping, and orthotics. In severe cases of heel pain, surgery may be required.

Preventing heel pain is possible.  If you are looking to prevent heel pain from developing in the future, be sure to wear shoes that fit you properly and do not have worn down heels or soles. Be sure to warm up properly before participating in strenuous activities or sports that place a lot of a stress on the heels. If you are experiencing any form of heel pain, speak with your podiatrist to determine the underlying cause and receive the treatment you need.
