Is it safe to burst a blood blister on a diabetics foot? if not what can you do for it?

A : A person with diabetes needs to be especially careful if a blister develops on the foot or toe. Sometimes a blister can lead to an ulcer in diabetics. If the blister makes it hard to walk, is painful or the area around it becomes red, swells or there is pus then you should have your podiatrist or your doctor check it out. If the blister is small, the contents will be reabsorbed back into the body.

It : It depends on how large the blister is and for how long it has been present. Usually, in diabetic patients, it might be better to leave the blister alone. Nevertheless, if there are signs of infection (redness surrounding the blister or pus drainage coming out), then it's better to burst the blister. In my practice, what i commonly do when I am faced with a diabetic patient who has a blood blister on his foot, i basically use a small scalpel to make a tiny incision into the blister, drain all the fluid that's inside, and then apply an antibiotic ointment with dsd over the skin. It is definitely not a good idea to try to remove the skin of the blister unless it appears very necrotic and loose.
