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.

When conservative, noninvasive treatments prove unsuccessful, podiatrists will often turn to surgery as the last line of treatment for their patients. If patients are suffering from joint pain, issues in mobility, or are seeking to correct a deformity, joint replacement surgery is an effective option. Joint replacement surgery is also successful in treating arthritis, which is the most common cause of improperly working joints.

Patients with symptoms that include joint pain, stiffness, limping, muscle weakness, limited motion, and swelling are typically considered for joint replacement surgery. Range of motion and activity post-surgery will vary between patients and depending on the specific surgery performed, the affected joint, and the damage that will need to be repaired.

Joint replacement surgery replaces the damaged cartilage and bone, the latter if required. The damaged cartilage is typically replaced with a prosthesis that is attached to the bone, allowing the implant to grow into the bone. Following surgery, the patient will typically undergo physical therapy to become familiar with movement using the replaced joint.

Morton’s neuroma, (also referred to as Morton’s metatarsalgia, Morton’s neuralgia, plantar neuroma or intermetatarsal neuroma) is a condition that is caused when the tissue around one of the nerves between your toes begins to thicken. This thickening can result in pain in the ball of the foot. Fortunately, the condition itself is not cancerous.

Morton’s neuroma affects women more often than men with a ratio of 4:1. It tends to target women between the age of 50 and 60, but it can occur in people of all ages. There are some risk factors that may put you at a slightly higher risk of developing the condition. People who often wear narrow or high-heeled shoes are often found to be linked to Morton’s neuroma. Additionally, activities such as running or jogging can put an enormous amount of pressure on the ligament and cause the nerve to thicken.

There usually aren’t any outward symptoms of this condition. A person who has Morton’s neuroma may feel as if they are standing on a pebble in their shoe. They may also feel a tingling or numbness in the toes as well as a burning pain in the ball of their foot that may radiate to their toes.

In order to properly diagnose you, the doctor will press on your foot to feel for a mass or tender spot. He may also do a series of tests such as x-rays, an ultrasound, or an MRI. X-rays are usually done to rule out any other causes for your foot pain such as a stress fracture. Ultrasounds are used to reveal soft tissue abnormalities that may exist, such as neuromas. Your podiatrist may want to use an MRI in order to visualize your soft tissues.

There are three main options for treatment of Morton’s neuroma: Injections, decompression surgery, and removal of the nerve. Injections of steroids into the painful area have been proven to help those with Morton’s neuroma. Decompression surgery has been shown to relieve pressure on the affected nerve by cutting nearby structures such as the ligaments in the foot. Another treatment option would be to surgically remove the growth to provide pain relief.

If you suspect that you have Morton’s neuroma you should make an appointment with your podiatrist right away. You shouldn’t ignore any foot pain that lasts longer than a few days, especially if the pain does not improve.

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.
