Blisters are small pockets of fluid that occur on the top layers of the skin for several reasons. Friction, burns, and diseases are all known causes of blisters.  Smaller blisters are known as vesicles, while larger blisters are referred to as bulla. The fluid inside the bubble can be blood, pus, or serum; which is a clear liquid that protects the skin. In most cases, blisters are not a major health issue, but they can be an indicator of a more serious condition.  

Causes of blisters vary. Blisters are commonly caused by wearing poorly fitted shoes that rub against the foot. However, there are many other causes besides from friction; including burns, sunburn, insect bites, frostbite, poison ivy/oak, chemical exposure, impetigo, eczema, viral infections, and more.

Most blisters heal by themselves and do not require immediate medical care. If you have a blister, do not pop it since this may cause infection; it is advised to put a bandage over the blister to protect it. If the blister is large, causes pain, or if you have a fever, it is recommended that you see a doctor who can provide proper care. Blisters are easy to diagnose, and if considered prudent by the doctor, can easily be drained of fluid with a sterile needle as well.

To prevent blisters on the feet, wear shoes that fit properly and don’t cause rubbing. Socks can help prevent friction and it is recommended that you wear them if you are wearing shoes. Hand blisters can be avoided by wearing gloves during activities that cause friction against the hand. If you have a blister that pops, do not remove the dead skin, wash the area, apply antibiotic ointment, and cover with a bandage. It is okay in most cases to not seek immediate medical care for a blister if it was just caused by friction. However, if the blister causes pain or does not go away, it is suggested that you see a doctor for a diagnosis.

Bunions are large bony bumps at the base of the big toe. Medically known as hallux valgus, a bunion is a misalignment of the metatarsophalangeal joint, or big toe joint. The misalignment will generally worsen with time if left untreated.

The exact cause of bunions is unknown, with genetics seen as a potential cause. High heels and poorly-fitted footwear, rheumatoid arthritis, and heredity all seem to be potential factors behind the exacerbation of bunions. Women have been found to be more likely to develop bunions in comparison to men.

Bunions do not always produce symptoms. The best way to tell is if the big toe is pushing up against the next toe and there is a large protrusion at the base of the big toe. You may or may not feel pain. Redness, swelling, and restricted movement of the big toe may be present as well.

Podiatrists use a variety of methods to diagnose bunions. If there are symptoms present, podiatrists will first consider that it is a bunion. If not, a physical examination will be conducted to check function of the big toe. Finally, an X-ray may be taken to view the extent of the bunion and confirm it is a bunion.

Typically, nonsurgical methods are used to treat bunions, unless the bunion has become too misaligned. Orthotics, icing and resting the foot, roomier and better fitted shoes, taping the foot, and pain medication are usually utilized first. If the bunion doesn’t go away or causes extreme pain, surgery may be required. Surgeons will either remove part of the swollen tissue or bone to straighten the toe out.

If you have a bunion, it is recommended to see a podiatrist. The longer it is left untreated, the worse it may get. Podiatrists can properly diagnose and treat a bunion before it gets worse.

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.

The Achilles tendon is the largest tendon in the body; it is a tough band of fibrous tissue that stretches from the bones of the heel to the calf muscles. This tendon is what allows us to stand on our toes while running, walking, or jumping, it is common for this tendon to become injured. In severe cases, the Achilles tendon may become partially torn or completely ruptured. However, this tendon is susceptible to injury because of its limited blood supply and the high level of tension it endures.

The people who are more likely to suffer from Achilles tendon injuries are athletes who partake in activities that require them to speed up, slow down, or pivot. Consequently, athletes who engage in running, gymnastics, dance, football, baseball, basketball, or tennis are more likely to suffer from Achilles tendon injuries. Additionally, there are other factors that may make you more prone to this injury. People who wear high heels, have flat feet, tight leg muscles or tendons, or take medicines called glucocorticoids are more likely to have Achilles tendon injuries.

A common symptom of an Achilles tendon injury is pain above the heel that is felt when you stand on your toes. However, if the tendon is ruptured, the pain will be severe, and the area may become swollen and stiff. Other symptoms may be reduced strength in the lower ankle or leg area, and reduced range of motion in the ankle. When the Achilles tendon tears, there is usually a popping sound that occurs along with it. People who have acute tears or ruptures may find walking and standing to be difficult.

If you suspect you have injured your Achilles tendon, you should see your podiatrist to have a physical examination. Your podiatrist will likely conduct a series of tests to diagnose your injury including a “calf-squeeze” test. Calf squeeze tests are performed by first squeezing the calf muscle on the healthy leg. This will pull on the tendon and consequently cause the foot to move. Afterward, the same test will be performed on the injured leg. If the tendon is torn, the foot won’t move because the calf muscle won’t be connected to the foot.

Sever’s disease, also known as calcaneal apophysitis is a common bone disorder that occurs during childhood. The disease is defined as an inflammation of the growth plate in the heel. When a child has a growth spurt, his heel bone grows faster than the muscles, tendons, and ligaments in his leg. This disease is a result of overuse. The people who are most likely to be affected by this disease are children who are in a growth spurt, especially boys who are from the ages of 5 to 13 years old. 60% of children with Sever’s disease have both heels involved.

Symptoms of this disease are heel pain that intensifies during running and jumping activities. The pain is typically localized to the posterior part of the heel. Symptoms may be severe, and they can easily interfere with daily activities. Children who play soccer, baseball, and basketball are more likely to develop Sever’s disease.

Your doctor will diagnose your child based on his or her symptoms, x-rays are generally not helpful in diagnosing this disease. Your doctor may examine both heels and ask your child questions about his or her activity level in sports. Your doctor may then use the squeeze test on your child’s heel to see if there is any pain. Nevertheless, some doctors might still use x-rays to rule out any other issues such as fractures, infections, and tumors.

Sever’s disease can be prevented by maintaining good flexibility while your child is growing. Another prevention method is to wear good-quality shoes that have firm support and a shock-absorbent sole. Sever’s disease can be treated by ceasing any activity that causes heel pain. You should apply ice to the injured heel for 20 minutes 3 times a day. Additionally, orthotics should be used for children who have high arches, flat feet, or bowed legs.

If you suspect your child has Sever’s disease, you should make an appointment with your podiatrist to have his or her foot examined. Your doctor may recommend nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen to relieve pain. In more severe cases, your child may need a cast to rest his or her heel. Fortunately, Sever’s disease does not cause long-term foot problems. After treatment, your child should start to feel better within two weeks to two months.
