What Is A Blister?

A blister is a pocket that is filled with air, serous fluid (lymph fluid), serum (blood) or serosanguineous (yellow fluid with streaks of blood). They are very commonly found on the heels, pinkie toes, elbows, or hands, but this will all depend on what causes them. Most blisters will not cause any type of complication, if they are properly treated. Below you will discover everything you need to know about the blister.

How do Blister Form

Blisters will form when the skin has become damaged. The epidermis (top layer of skin) will become loosened and lymph fluid or air will build up between the epidermis and dermis (second skin layer).

Why do Blisters Form

Blisters are most caused by friction or continuous rubbing force. This can occur when two areas of your skin rubs together such as your thighs. There are other factors that are linked to blisters as well including sunburns, acne, cellulitis, burns, freezing, chemical exposure, or viral and bacterial infections.

Types of Blisters

  • Bullae is one large blister that measure over 1cm horizontally
  • Abscess (boil) is a often found in deeper skin tissues and will contain bacterial infected fluids.
  • Friction blister
  • Blood blister will contain serosanguineous fluids

Blisters on feet are often caused by wearing the improper shoe size, pumps, and stilettos.

How To Cure Blisters

Healing blisters is not that difficult, if you choose the right products.

Dealing with Blisters

While it is best to avoid popping the blister sometimes it becomes necessary, in order to wear your shoes or just to decrease the pain. You will need to gather your supplies, before you get down to business. Sterilized darning needle will work the best and you can use isopropyl alcohol to sterilize the tip of the needle. Make sure that your hands have been washed thoroughly with anti-bacterial soap and water.

Lay out several layers of paper towel to catch the fluid, so it does not get on your clothing or furniture. Stick the top of the needle into the blister, but only deep enough to open the blister up. Once the fluid starts to seep out of the blister, you can take your fingers and push the fluid out the pin-sized hole.

Wash the affected area thoroughly with soap and water, then dry it very well and place a Compreed Blister Plaster on top of it.
