Blisters are pockets of fluid that occur under the top layer of your skin. These fluid pockets are usually filled with pus, blood, or serum. Blisters may itch or hurt and can appear as a single bubble or in clusters.
The most common types of blisters are friction blisters. This type of blister may be caused by wearing shoes that are too tight. Friction blisters can also occur on the hands. A change in temperature may also cause blisters on the feet. In the freezing air, frostbite on your toes can lead to blisters, as well as sunburn from hot weather.
The best way to treat a blister is to keep it clean and dry. Most blisters will get better on their own. Once the skin absorbs the fluid within the blister, it will flatten and eventually peel off. You should avoid popping your blister unless you podiatrist does it for you. Additional treatment options include applying an ice pack to the blister or using over-the-counter blister bandages to cover the affected area.
If your blister becomes discolored, inflamed, or worsens it is advised that you speak to your podiatrist. Blisters that are yellow, green, or purple may be infected and require immediate medical attention. Blisters that are abnormally colored may be a sign of a more serious underlying health condition such as herpes.
Tarsal tunnel syndrome is a condition in which the tibial nerve, located in the tarsal tunnel in the foot, is compressed. The tibial nerve can become compressed from injury, such as an ankle sprain, flat feet, and lesions. Arthritis, diabetes, and varicose veins can also cause swelling and thus result in nerve compression.
Symptoms of tarsal tunnel syndrome include several different sensations in the sole of the foot, inside the ankle, and around the tibial nerve. These sensations include shooting pains, numbness or reduced sensation, pins and needles, burning, and tingling. Symptoms tend to worsen with greater activity to the area. In rare and severe occasions, this can change the muscles in the foot.
If you suspect you have tarsal tunnel syndrome, you should consult with your podiatrist. He or she will examine your medical history to see if you have a history of diabetes, arthritis, or flat feet. They will also check to see if you have suffered an injury to the area recently. An electrical test will be conducted to check if the nerve has been damaged. A simpler Tinel’s Test might also be used. This includes simply tapping the nerve to create a sensation. An MRI scan of the area may also be used.
Treatments vary greatly for tarsal tunnel syndrome. Treatments include both nonsurgical and surgical options depending upon the severity of the condition. Nonsurgical options include anti-inflammatory medication and steroid injections to the area. Orthotics, such as a splint or brace that immobilizes the foot, is another noninvasive option. For those with flat feet, custom shoes can be made to offer better foot support. Surgical options include a tunnel tarsal release, in which an incision is made behind the ankle down to the arch of the foot. This releases the ligament and relieves pressure off the nerve. Some doctors use a more minimally invasive surgery, where smaller incisions are made in the ankle and the ligament is stretched out.
If you are suffering from painful sensations in your foot, see a podiatrist who can determine if you are experiencing tarsal tunnel syndrome. Tarsal tunnel syndrome that is left unchecked can cause permanent nerve damage to the foot.
Walking Shoes vs. Running Shoes
Although walking shoes and running shoes look similar, they have characteristics that make them different from each other. Runners should avoid running in walking shoes and vice versa. It is very important that you wear the proper footwear for the activity you are going to partake in, for you to avoid injury.
If you are looking to buy a new pair of running shoes, there are certain things you should look out for. One of the main components that makes up a good running shoe is flexibility. You should be able to bend and flex the forefoot of the shoe that you are purchasing. If you can bend the entire shoe in half with ease, this is a sign that the shoe does not have enough structure for your feet. Another feature you should look for is a low heel. Certain running shoes have a low heel to support runners who land on the ball of their feet. Lastly, you should look for the fit of the running shoe. You should visit the best running shoe store in your area to have your feet properly sized for the shoes in the store. Usually, the staff will be able to help recommend the best type of running shoe for your needs.
When you are walking, the body’s weight is evenly distributed on the foot. This influences the design of shoes made for walking. If you are looking to buy a pair of walking shoes, there are different features you should look for to determine which pair of shoes is best for you. Walking shoes should be flexible through the ball of the foot to allow for a greater range of motion through the roll of the forefoot. These shoes also should have greater arch support for the foot. If you plan on walking long distances or on hard surfaces, it is best that you wear shoes that have cushioning.
When trying on a new pair of shoes, the heel should fit snugly without slip. You should shop for shoes after a long walk, since your feet tend to swell throughout the day. Many people have one foot that is a different size than the other, so it is best that you have both feet measured when looking for your true size. You should also beware that sizes vary depending on the shoe brand. A certain size in one brand may be a different size in a different brand. Lastly, you should always walk around in shoes that you plan on buying. This will help you determine whether the shoes are comfortable and if they fit well on your feet.
Always look for good shoe construction when shopping for new sneakers. The upper part of the shoe should allow for adjustment through laces or straps. If you need help with shoe sizing or if you need custom orthotics for your feet, you should make an appointment with your podiatrist for assistance. He or she will be more than happy to help you with your shoe sizing needs.
A podiatrist is a doctor of podiatric medicine who treats the foot, ankle, and related structures of the leg. If you are having any pain, injuries, or abnormalities in these areas, it is best that you seek help from a podiatrist.
Podiatrists complete four years of training in a podiatric medical school. Their training is like that of other physicians, and they may go on to complete a fellowship training after a residency training. Some podiatrists are board certified meaning they have advanced training, clinical experience, and have taken an exam to prove their skills. Certifying boards for podiatry are the American Board of Foot and Ankle Surgery and the American Board of Podiatric Medicine. Podiatrists may work in private practices, hospitals, clinics, or they may even become professors at colleges of podiatric medicine.
While in college, those who want to be podiatrists often take biology, chemistry, and physics classes in preparation for podiatry school. In podiatry school, students study how the bones, nerves, and muscles work together to help you move around. Additionally, they study injuries and how to properly diagnose and treat them. Admittance into podiatric medical school requires the completion of 90 semester hours of undergraduate study with a good grade point average, and acceptable scores on the MCAT (Medical College Admission Test)
Podiatrists treat many different conditions such as: aching feet, ankle pain, bunions, corns, hammertoes, fungus, ingrown toenails, plantar fasciitis, sprains and more. Common forms of treatment for these conditions are physical therapy, drugs, or surgery. Podiatrists may also recommend corrective shoe inserts, custom-made shoes, plaster casts, and strappings to correct deformities.
Even if you are someone whose feet are in generally good condition, you should still visit a podiatrist to have your feet properly exfoliated and maintained, or to make sure you are looking after your feet properly.
