I,unexpectedly spent 3 hours outside in a tank top last week. My back and shoulders were sunburned badly. Parts of the burn have peeled, but there s a large area that s scaly/crunchy to the touch and has patches of brown discoloration. The pain has actually subsided fairly well, and ample aloe vera helps with any itching and burning. But the skin looks so damaged, and is very tight with a tingling sensation. Is this just a bad burn that will heal with time, or is it time to see a doctor?
