Blisters: To Pop or not To Pop!

Foot BlistersYikes! Nothing hurts quite like a blister or blisters on your feet! Blisters may not be life-threatening, but they sure are a pain! It’s never fun dealing with a blister.

What Exactly is a Blister?

A blister is a small bubble on the skin filled with serum and can be caused by friction, burning, or other damage.

Blisters can also form from fungal infections, allergic reactions, and burns. Poor-fitting shoes are usually the culprit in blisters forming!

I often get asked what exactly is the fluid inside a blister. Blister fluid (serum) is clear liquid that seeps from the body’s surrounding tissues to fill the blister. This serum protects the skin beneath the bubble. The skin of the bubble and the serum also work together to help the injured skin below to heal properly.

Blister Care

Minor or small blisters usually heal well on their own and the fluid is reabsorbed by your body. It’s best to just leave them alone.

If the blister is large, slow to heal, or appears red, irritated and the fluid has turned white, red,  or yellow, medical attention may be warranted, particularly if you’re diabetic.

Diabetics should never try to treat a blister on their own. Any injury to the foot, no matter how small, warrants a trip to the podiatrist to get it carefully examined and treated.

And, due to a condition called neuropathy, or nerve damage, some people, including diabetics, often are unable to even detect the presence of a blister. This is why diabetics need to inspect their feet regularly, or have someone inspect them for them.

With large  blisters, I would drain the fluid but leave the “skin” intact in order to protect the skin underneath. I would also use a non-stick bandage with mild compression to protect it.  If there is a lot of pain, or redness around the area after it is drained, seek medical attention promptly.
