I walk a lot. And occasionally do some running (typically alternating with walking). Today, I have a small blister on the underside of my foot. Being ever curious, I began to explore the available literature about foot blister risk reduction and management. Have you ever had a blister that ruined a run or a race? Or that just nagged at you at a low level for a couple of days?
If you have formed a small pocket of fluid on some part of your body, you may have had a blister. These bubbles vary in size and have many causes. For example, you may get one after infection, trauma, or even an insect bite. The location of it can influence the effects on your quality of life. For example, foot blisters may lead to challenges in walking, standing, or exercising.
Let’s turn to some of the causes of blisters. For ones on foot, friction is often the causative agent. Walk or stand for hours, and you put pressure on various parts of your feet, including the heels, toes, and soles. Poorly fitted shoes may result in fluid-filled bubbles, whether the shoes are too tight or too loose. The resultant friction causes a fluid buildup just beneath the upper layer of the skin.
Other potential causes include:
Usually, blisters on the feet that result from friction will spontaneously resolve after a few days. If they don’t heal over time or in response to treatment, please see a valued healthcare professional, particularly if you have severe pain, fever, nausea, or chills. You may have an infection. A doctor or other healthcare professional may drain the blister using a sterile needle. If she suspects an infection, the fluid can be examined to get to the root causes.
Why yes. First, don’t pick at the blister or burst it. If you do so, you may cause an infection. First, many blisters that are left alone will eventually harden and go away. However, in the interval, you may experience discomfort, depending on the size and location of the lesion. Instead of bursting it, Healthline suggests these steps to properly train a blister at home:
