Blisters are a common ailment of people who wear shoes that are either too tight or rub against the feet in an uncomfortable way. Knowing the basics of blisters is important for understanding how they are formed and what treatments should be used for them.

A blister on the foot, or any other part of the body, is a small pocket that is filled with fluid. It usually forms on the upper layer of the skin because these layers are loose enough to allow a blister to form. The most common fluid in a blister is just a clear, watery-like fluid that usually isn’t cause for concern. However, blisters can fill up with blood if they are deep enough and pus if they have become infected with bacteria.

Blisters almost always form on the feet due to shoes rubbing up against the foot, where the friction causes blisters. These can occur after you have walked for a long period of time or when your shoes do not fit you properly. Your feet are also more prone to blisters if they are moist, so keeping them dry and clean is one preventative step you can take.

Preventing infection should be the number one concern when treating blisters, as well as relieving the pain they can cause. Using a bandage to cover up the blister will help it heal and prevent bacteria from entering it. New skin will form under the blister and eventually cause it to pop. You can also take a sterilized pin and try to pop it yourself.

If the blister is filled with pus or blood, seeking treatment from a doctor is ideal. Antibiotics may need to be taken in order to completely eliminate the bacteria inside the blister. See a doctor to have an antibiotic prescribed.

The best way to treat blisters is to prevent them all together. Keeping your feet dry and making sure that your shoes fit properly are just two of the steps you can take to prevent blisters. Shoes that are too tight or shoes that are too loose and allow your feet to slide in them will cause blisters. Applying a bandage to an area where you think a blister is about to form is another way you can prevent them.

Plantar hyperhidrosis, or hyperhidrosis of the feet, affects approximately 1-2% of Americans. Plantar hyperhidrosis is characterized by excessive sweating in the feet not set by other causes such as exercise, fever or anxiety. Many people affected by plantar hyperhidrosis also suffer from palmar hyperhidrosis, or excessive seating of the hands, in addition.

Normally sweating is a process used by the body’s sympathetic nervous system to cool itself and maintain a steady internal temperature. In individuals affected by hyperhidrosis, the sympathetic nervous system produces far more sweat than actually needed.

Plantar hyperhidrosis is considered a primary hyperhidrosis, as secondary hyperhidrosis refers to excessive sweating in areas other than the feet, armpits or hands. Secondary hyperhidrosis could indicate other medical conditions such as Parkinson’s disease, hyperthyroidism and menopause.

Symptoms of plantar hyperhidrosis include athlete’s foot, infections, blisters and foot odor. Due to the continual moisture, socks and shoes can rot, creating an additional odor that can ruin the materials and cause socks and shoes to need frequent replacement. In addition to physical symptoms, this disorder can also affect emotional health as this disorder can be embarrassing.

Hyperhidrosis can persist throughout an individual’s life if left untreated. Fortunately, there are several treatment options available. A common first approach is using a topical ointment often containing aluminum chloride, an ingredient found in antiperspirants. Another treatment method is using Botox, which is injected directly into the foot, and can effectively minimize the sweat glands in the injected area. These injections need to be repeated every 4 to 9 months.

If either of these treatments prove ineffective, oral prescription medications may be taken to alleviate the symptoms. As with any treatment, some will experience relief while others do not. Another method that reportedly provides relief is going barefoot.

A final approach to fighting plantar hyperhidrosis is through surgery, although it is less successful on those with hyperhidrosis in the feet as opposed to hands. Surgery is only recommended when the sweating is severe and other treatments have failed to work. This type of surgery involves going into the central nervous system and cutting nerves to stop transmission of signals telling the foot to sweat. 

Foot and ankle injuries are common among people who participate in sports. Several factors contribute to this. They include failing to stretch or warm up properly, not wearing the proper type of shoe and not taping or providing other types of support for the ankle or foot. The most common foot and ankle injuries suffered by people involved in sports are plantar fasciitis, ankle sprains and Achilles tendon damage or ruptures. If not treated properly, they can lead to permanent disability.

Treating these injuries is relatively simple if they are identified and addressed early. Many athletes dismiss the initial aches and pains associated with injury as just soreness or tired muscles. Their first response is usually to try to work through it. This can lead to serious problems. Many minor injuries are made far more serious when athletes continue to put strain and pressure on them. That attitude can change a mild strain into a serious strain and a minor tear into a rupture. Athletes should have unusual aches and pains evaluated by a skilled medical professional.

Plantar fasciitis is a painful injury. It is inflammation of the plantar fascia, the thick band of tissue running from the heel to the base of the toes. If left untreated, it can lead to a degenerative disease called plantar fasciosis. There are several effective treatments for this ailment. Doctors often prescribe rest, massages, stretching, night splints, physical therapy, anti-inflammatory medication, corticosteroids or surgery, usually in that order. The most effective treatment for plantar fasciitis is orthotics, which offers foot support. Surgery is occasionally used as a last resort, but it comes with the risk of nerve damage and infection and often does not stop the pain.

The Achilles tendon is the largest tendon in the body. It connects the calf muscles to the heel bone. Running, jumping and walking all impact this tendon. Two common injuries to the Achilles tendon are tendonitis and a rupture of the tendon. Tendonitis is inflammation in the tendon often caused by an increase in the amount of stress placed on it. Non-surgical treatmentsinclude rest, ice or anti-inflammatory medication. A rupture (tear) of the Achilles tendon can be treated by placing the lower leg in a cast for several weeks or with surgery. Many physicians feel surgery is the better option because it lowers the risk of re-ruptures. Both methods require 4 to 6 months of rehabilitation.

Ankle sprains are the most common sports related foot and ankle injury. A sprain occurs when the ligament holding the ankle bones and joint stretches beyond its normal range. It can be treated non-surgically with a combination of rest, ice wrapped around the joint for 30 minutes immediately after injury, compression by a bandage and elevating the ankle above the heart for 48 hours. This combination is referred to as RICE. Severe ankle sprains in which the ligaments are torn may require reconstructive surgery followed by rehabilitation.
