6 days ago I fell and landed in poison ivy. I use ivydry and tecnu to cover the rashes. I take Benadryl all the time and that kind of helps. The rash is in both of my inner thighs and my cheeks. The rash on my thighs are really stiff when I move or walk. The skin is dry and flaky. The blisters have a yellowish color. I need to know if these are signs of it healing??
