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.

A bunion is an enlargement of the base joint of the toe that connects to the foot, often formed from a bony growth or a patch of swollen tissues. It is caused by the inward shifting of the bones in the big toe, toward the other toes of the foot. This shift can cause a serious amount of pain and discomfort. The area around the big toe can become inflamed, red, and painful.

Bunions are most commonly formed in people who are already genetically predisposed to them or other kinds of bone displacements. Existing bunions can be worsened by wearing improperly fitting shoes. Trying to cram your feet into high heels or running or walking in a way that causes too much stress on the feet can exacerbate bunion development. High heels not only push the big toe inward, but shift one's body weight and center of gravity towards the edge of the feet and toes, expediting bone displacement.

A podiatrist knowledgeable in foot structure and biomechanics will be able to quickly diagnose bunions. Bunions must be distinguished from gout or arthritic conditions, so blood tests may be necessary. The podiatrist may order a radiological exam to provide an image of the bone structure. If the x-ray demonstrates an enlargement of the joint near the base of the toe and a shifting toward the smaller toes, this is indicative of a bunion.

Wearing wider shoes can reduce pressure on the bunion and minimize pain, and high heeled shoes should be eliminated for a period of time. This may be enough to eliminate the pain associated with bunions; however, if pain persists, anti-inflammatory drugs may be prescribed. Severe pain may require an injection of steroids near the bunion. Orthotics for shoes may be prescribed which, by altering the pressure on the foot, can be helpful in reducing pain. These do not correct the problem; but by eliminating the pain, they can provide relief.

For cases that do not respond to these methods of treatment, surgery can be done to reposition the toe. A surgeon may do this by taking out a section of bone or by rearranging the ligaments and tendons in the toe to help keep it properly aligned. It may be necessary even after surgery to wear more comfortable shoes that avoid placing pressure on the toe, as the big toe may move back to its former orientation toward the smaller toes.

Peripheral artery disease (PAD), or peripheral arterial disease, is a circulatory problem in which there is a reduction of blood flow to the limbs due to narrowed arteries. When peripheral artery disease develops, the extremities do not receive enough blood flow; this may cause symptoms to develop such as claudication, or leg pain when walking. The legs are the most common site of peripheral artery disease.

Claudication, or leg pain when walking, is one of several symptoms that can develop due to peripheral artery disease. Other symptoms caused by the disease include painful cramping in the hips, thighs, or calves after certain activities; leg numbness or weakness; coldness in the lower leg or foot; sores on the lower extremities that do not heal; hair loss on the lower extremities; and a missing or weak pulse in the lower extremities. In more severe cases, pain may even occur when the body is at rest or when lying down.

Peripheral artery disease is typically caused by atherosclerosis, a condition in which fatty deposits build up in the arterial walls and reduce blood flow. Smoking, diabetes, obesity, high blood pressure, and high cholesterol are some of the risk factors for peripheral artery disease.

If you are experiencing pain, numbness, or other symptoms in the lower extremities, see your healthcare professional immediately. Diagnosed peripheral artery disease can be treated with various medications, angioplasty and surgery, exercise programs, or alternative medicine. It is important to consult a healthcare professional to determine the best treatment for you.

While not a serious issue, toenail fungus, or onychomycosis, can be an embarrassing and uncomfortable condition to experience. Toenail fungus is often caused from public areas that harbor fungi and improper cleaning/drying of the foot. Once infected, the fungus grows deeper into the nail and can be very hard to get rid of.

There are different types of fungus that cause toenail fungus. Dermatophytes, yeasts, and molds are the most frequent forms of fungus to infect the toenail. Dermatophytes are the most common among the three. Symptoms associated with fungal nails include the discoloration of the toenail, brittleness, and in some circumstances, a smell. Pain is rarely a symptom caused by toenail fungus.

Diagnosis of fungal nails is generally a rather quick process. However podiatrists will make sure that the cause is not another condition such as lichen planus, psoriasis, onychogryphosis, or nail damage. Podiatrists will make use of fungal cultures and microscopy to verify that it is fungus.

While over-the-counter ointments are readily available, most are ineffective. This is due to the fact that the nail is very protective and that the fungus slips in between the nail plate and bed. Podiatrists can offer oral medication which currently provides the best results.

Ultimately, prevention is the best line of defense against toenail fungus. Avoid unsanitary public showers. If you do use a public shower, use shower shoes to provide your foot with protection. Once you are finished showering, make sure to thoroughly dry your feet. Fungi thrive in warm, dark, and moist places like sweaty, warm feet that are left dark in shoes all day.

Corns are thickened areas on the skin’s surface, to the point of being irritating and sometimes painful. Commonly found on the feet, corns are circular or cone-shaped. They develop where there are areas of pressure or friction, such as on the little toe when it rubs up against shoes, or on the ball of your foot.

Corns are often confused with a callus, but there is a difference between them. Corns can be raised bumps that are painful to the touch. They consist of a rough, thick area of skin that may be dry or waxy. Corns tend to be surrounded by skin that is inflamed, and are usually much smaller than calluses.

Removing the dead skin that has built up is the key in treating corns. Salicylic acid medication is most common in accomplishing this. The acid works by dissolving keratin, which is the protein that makes up the majority of corns. You can purchase salicylic acid over-the-counter in products such as wart removers. It comes in a variety of forms such as medicated pads, drops, or creams. However, people who are diabetic should not use salicylic acid, but should instead consult their doctor immediately.

According to the product directions, applying the medication directly onto the corn will treat it. The top layer of the corn will begin to turn white after use. When that occurs, the layers of skin can then be peeled away, making the corn smaller. Shaving off corns with razors or other pedicure equipment is never a good idea. This can lead to infection. If your corn gets infected, and is not treated immediately, a visit to the doctor will be necessary.

Another way to treat corns and help prevent their return is by using orthotic inserts, fitted by a podiatrist. Inserts fit right into your shoes and adjusts the way your foot fits into your shoes. This fixes the way you walk. This will lower your chances of getting corns, and eliminate current corns by reducing rubbing from friction.

Surgery is rarely used to treat corns, but does occur on occasion. Surgery actually deals with the underlying issue that causes corns. During surgery, the bone is shaved and any abnormalities are corrected, thus reducing the amount of friction that occurs during walking.

To prevent corns, the first step is reducing friction. Always wear shoes that fit well and don’t rub your feet. Pads can be purchased if you notice rubbing developing. These pads can be purchased over-the-counter, and can be simply placed on the irritated area. Wearing cushioned insoles in your shoes can always reduce the friction, and making sure to wear well-fitting shoes. This will ensure that your foot is not being squeezed awkwardly, and prevent corns from forming in the first place.
