Most blisters are caused by friction or minor burns and do not require medical attention. New skin will form underneath the affected area and the fluid is simply absorbed. You can soothe ordinary blisters with vitamin E ointment or an aloe-based cream. We recommend not to puncture a blister unless it is large, painful, or likely to be further irritated.
Heat, moisture and friction are generally the cause of blisters. Blisters can also form from fungal infections, allergic reactions, and burns. Because of a condition called neuropathy, or nerve damage, diabetes often are unable to detect a burn because there is no pain. Proper care of blisters should involve draining their fluid but leaving their “skin” intact. Protect with a non-stick bandage with mild compression. Skin sprays and adhesive gel pads, as well as special socks, help minimise friction.
