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.
Heel spurs are the result of calcium deposits that cause bony protrusions on the underside of the heel. Heel spurs are usually painless, but they have the potential to cause heel pain. Heel spurs tend to be associated with plantar fasciitis, which is a condition that causes inflammation of the band of connective tissue that runs along the bottom of the foot. They most often occur to athletes whose sports involve a lot of running and jumping.
Some risk factors for developing heel spurs include running and jogging on hard surfaces, being obese, wearing poorly fitting shoes, or having walking gait abnormalities.
It is possible to have a heel spur without showing signs of any symptoms. However, if inflammation develops at the point of the spur’s formation, you may have pain while walking or running. In terms of diagnosis, sometimes all a doctor needs to know is that the patient is experiencing a sharp pain localized to the heel to diagnose a heel spur. Other times, an x-ray may be needed to confirm the presence of a heel spur.
Heel spurs can be prevented by wearing well-fitting shoes that have shock-absorbent soles. You should also be sure that you are choosing the right shoe for the activity you want to partake in; for example, do not wear walking shoes when you want to go on a run. Additionally, maintaining a healthy weight can be beneficial toward preventing heel spurs, as it will prevent an excess amount of pressure being placed on the ligaments.
There are a variety of treatment options for people with heel spurs. Some of these include stretching exercises, physical therapy, shoe inserts, or taping and strapping to rest stressed muscles and tendons. If you have heel pain that lasts longer than a month, don’t hesitate to seek help from a podiatrist. Your doctor can help you determine which treatment option is best for you.
Diabetics must be wary of all wounds, regardless of depth or size. Diabetes, a chronic disease in which the body cannot properly use glucose the way it normally would, causes various complications that make wounds difficult to heal. Nerve damage or neuropathy will cause diabetics to have trouble feeling the pain of a blister or cut until the condition has significantly worsened or become infected. A diabetic’s weakened immune system can make even the most minor of wounds easily susceptible to infection. Diabetics are also more prone to developing narrow, clogged arteries, and are therefore more likely to develop wounds.
Wounds should be taken care of immediately after discovery, as even the smallest of wounds can become infected if enough bacteria build up within the wound. To remove dirt, wounds should be first rinsed under running water only. Soap, hydrogen peroxide, or iodine can irritate the injury and should be avoided. To prevent infection, apply antibiotic ointment to the wound and cover it with a bandage. The bandage should be changed daily. The skin around the wound may be cleaned with soap.
To prevent further exacerbation, see a doctor—especially if you have diabetes. Minor skin conditions can become larger problems if not properly inspected. As the wound heals, make sure to avoid applying pressure to the affected area.
A plantar fibroma is a knot in the arch of the foot. It can cause pain when repeated pressure is applied by walking barefoot or wearing tight shoes. While plantar fibromas can appear in anyone, men who are middle-aged or older are said to be more susceptible. The main symptom of a plantar fibroma is a firm lump on the arch of the foot. If there is pain, it can be intensified by putting pressure on the nodule. The lump can stay one size or grow larger. You may have one or more fibromas in the feet and there tends to be a high incidence of recurring plantar fibromas. Generally, a plantar fibroma can be treated without surgery. Treatment might include steroid injections to help shrink the lump, orthotics to help redistribute weight away from the nodule, plantar fascia stretching, or physical therapy to help use anti-inflammatory medication on the lump. If a lump grows larger or more painful, a podiatrist can be consulted to confirm the diagnosis. The doctor will palpate the lump and this may cause pain that can be felt all the way to the toes. An X-ray, MRI, or biopsy might be done if further evaluation is necessary. A lump in the arch of the foot might be something other than a plantar fibroma, such as cysts, nerve or fatty tumors, swollen tendons, or an infection in the foot. It is important to see a podiatrist for proper diagnosis and treatment of plantar fibromas.
