Blisters often occur when feet are in shoes that are tight or in situations where excessive friction builds up within the shoe. The sock and foot then rub against each other on the inside of the shoe. Fluid fills up a space between layers of skin to protect the area, like a small balloon. That's how a blister forms. People with diabetes may not be able recognize the painful event due to a condition called neuropathy (loss of sensation) these patients should have blisters professionally treated to avoid any risk of infection.
Sometimes these blisters "pop" by themselves and can become infected. Watch out for redness or leaking yellow liquid, and for red lines near the blister. These are symptoms that require medical attention. If the blister has not "popped," then leave it alone. Most of the time it will reabsorb and heal on its own.
If you are constantly developing blisters it may be a symptom of a biomechanical problem. You should visit your Podiatrist and have a professional gait assessment. |
