hello i have these wierd blisters on my skin that dont heal as fast as other cuts on my body. Ive also noticed that there are small brown patches forming in the same areas as the blisters. Their shapes are not uniform and each is no bigger than the end of a toothpick. They started on the back of my hands and then my knees now my feet. They are relatively spread out as they dont seem to have slowly spread from my hands to my knees or my knees to my feet. The brown patches neither itch nor hurt to the touch, and the blisters hurt when i touch them but only as much as a small infection. If you have any idea of cases like this where i could look at pictures and try to identify it please let me know.
