With the change of seasons and activities means a change of footwear into netball or football boots for example. This change increases the number cases of blisters. A blister caused by continued rubbing basically separates the top layer of skin (epidermis) from the lower level (dermis). This separation then fills up with a clear fluid. This process while due to friction forces is actually a defensive mechanism of the body so is a natural response.
Should I pop a blister?
In most cases it is better to leave the blister, as it will heal itself. The fluid is reabsorbed into the body
When should I pop a blister?
There are some blisters that may need to be popped, but this must be done with extreme caution and seek professional advice. The reason is once a blister is popped the clear fluid is drains out which happens to be sterile, and if the top layer skin is removed, it actually leaves a entry for micro organisms to enter our system, increasing infection risk.
Make sure the shoe fits, this is obvious. When you get any new footwear home wear them for a short period to see if you can feel any danger points, where a blister may form. If you feel it is rubbing then slowly break in the footwear and apply a second skin to the areas that are at risk. A second skin can be a plaster but I prefer sports tape. You can also apply a petroleum jelly to help the material to glide over the skin. One caution to note is to make sure you have no allergy to tape adhesive.
