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.

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 treatments include 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.

Overtraining and overusing the feet are the main causes of common running injuries. A number of these common injuries are caused by overrunning. Runner’s knee is a condition that is characterized by the back of the kneecap beginning to wear away and cause pain in the knee. This frequently occurs due to either a decrease in strength in the quadriceps muscles or ill-fitting shoes that are lacking in proper support for the inside of the forefoot. Strengthening exercises focusing on the quad muscle and sports orthotics are the usual treatments for those suffering from runner’s knee. Prevention of the condition lies in a focus on hip strengthening and quad-strengthening to keep the kneecap aligned. To help learn the best exercise to heal runner’s knee, one can also undergo physical therapy.

One common injury, called iliotibial band syndrome, is often caused by overtraining. This condition occurs when the iliotibial band gets irritated, creating pain and discomfort in the outside knee area. Plantar fasciitis, another common running injury, also occurs as a result of inflammation and irritation. Plantar fasciitis is an inflammation and irritation of the bone in the foot. A large amount of pain is often experienced due to plantar fasciitis. The condition can be caused by a high arch, improper footwear, tight muscles, or flat feet. It can best be avoided by stretching and wearing appropriate footwear that supports the foot.

Another common injury for runners is stress fractures. These injuries occur due to running style, overtraining, or a lack of calcium. Stress fractures most often occur in several locations in runners, including the inner bone of the leg, the thighbone, the bone at the base of the spine and the bones of the toes. Stress fractures are best prevented by wearing proper footwear and by running on flat and hard surfaces; this will absorb some of the shock created during running.

Aside from overtraining, other causes of common running injuries include ill-fitting footwear, a lack of flexibility and strength, and irregular biomechanics. The best way to avoid running injuries is to prevent them from even occurring. Both iliotibial band syndrome and stress fractures are preventable. The first step that should be taken to prevent running injuries is to only wear footwear that fits properly and that is appropriate for whatever activity you are doing. Running shoes are the only protective gear available to runners that can safeguard them from sustaining injuries. Choosing the right pair of shoes is therefore extremely important. While running shoes are an important factor, it is also important to consider other facets of your running routine such as training schedules, flexibility, and strengthening. These elements should be considered and altered according to your running needs to best maximize your run and minimize the possibility of injury. Careful stretching before and after a run should also be considered to help prevent running injuries. Stretching muscles enables greater flexibility and a lesser chance of sustaining injury.

Toe pain can originate from corns, calluses, hammertoes, and bunions, as well as ingrown toenails, sprains, fractures, and dislocations. Corns develop as the toe rubs against the inside of a shoe which causes the skin to thicken as a form of protection. A corn is typically cone-shaped and has a small, hardened spot that points inward. When a corn is pressed into the skin, the toe becomes painful. Corns usually form on the top or side of the toe. A callus is also a thickened patch of skin that generally forms on the bottom of the foot. Calluses are the result of friction from the toe rubbing against the inside of a shoe. They may also occur by walking barefoot or having flat feet. A hammertoe is a bump on the knuckle of the second toe that is produced by wearing shoes that are too short for your feet. The bony protrusion rubs against the top of the shoe causing pain and irritation. A bunion is a malformation of the big toe. The base of the big toe pushes away from the smaller toes, forcing the top of the big toe to press toward the other toes. Bunions can be hereditary, or they can result from injury to the toe joint or from wearing high heels with a narrow toe box. The toe becomes inflamed, and a bump may develop at the end of the misplaced bone. Ingrown toenails typically affect the big toe and its surrounding skin. The nail will dig into the skin and become painful. Wearing tight or narrow shoes that compress the big toe causes the nail to grow into the fleshy part of the toe. Cutting toenails incorrectly can also add to the development of an ingrown toenail. A toe sprain originates from a torn or stretched ligament. Strapping the injured toe to the toe next to it for stabilization is common. A broken or fractured toe usually occurs from trauma like dropping a heavy object on it or bumping into something extremely hard and rigid. Osteoporosis, a thinning of the bones, can also bring about toe fractures. 

Any of the conditions mentioned can lead to pain and irritation. While some are more serious than others, seeking an examination and diagnosis from a podiatrist is a good idea. A podiatrist can treat each ailment and get you back on your feet again without pain.

Flatfoot is a foot disorder that is not as straightforward as many people believe.  Various types of flatfoot exist, each with their own varying deformities and symptoms.  The partial or total collapse of the arch, however, is a characteristic common to all types of flatfoot.  Other signs of flatfoot include:

• “Toe drift,” or the pointing outward of the toes and the front part of the foot
• The tilting outward of the heel and the tilting inward of the ankle
• The lifting of the heel off the ground earlier when walking due to a tight Achilles tendon
• Hammertoes
• Bunions

One of the most common types of flatfoot is flexible flatfoot.  This variation usually starts in childhood and progresses as one ages into adulthood.  Flexible flatfoot presents as a foot that is flat when standing, or weight-bearing.  When not standing, the arch returns.  Symptoms of flexible flatfoot include:

• Pain located in the heel, arch, ankle, or along the outside of the foot
• Overpronation, or an ankle that rolls in
• Shin splint, or pain along the shin bone
• General foot aches or fatigue
• Pain located in the lower back, hip, or knee

Your podiatrist will most likely diagnose flatfoot by examining your feet when you stand and sit.  X-rays may be taken to define the severity and help determine the treatment option best for your condition.  Nonsurgical treatments can include activity modification, weight loss, orthotics, immobilization, medications, physical therapy, shoe modifications, and ankle foot orthoses (AFO) devices.  If nonsurgical methods prove ineffective, surgery may be considered.  Multiple surgical procedures can correct flatfoot; and depending on your specific condition, one may be selected alone or combined with other techniques to ensure optimal results.
