1 Pemphigus vulgaris, a potentially fatal skin disease, causes blisters in the mouth or skin; these painful blisters become raw and crusted after bursting.  Bullous pemphigoid causes less severe blisters that heal faster and are not life-threatening; this condition is seen mostly in elderly people.
This problem is caused by friction from your shoes or clothing rubbing repeatedly against your skin, causing friction burns. Friction blisters manifest when the outer layer of your skin separates from your inner layer of skin and the space between these two layers fills with lymph fluid.
