Help!?!?! Pleaseeee!!

Ashlyn
Okay so, 6 days ago I got a pretty bad sunburn. I went to the doctor 2 days after and they gave me cream to put on it to heal. It worked fine I'm still red all over but I dont hurt at all or burn or anything. There's blisters on my back but they don't hurt (oddly). And if course I'm itchy now and peeling in places, but yesterday i noticed ny foot and ankle was swelling (A LOT) & today it's EVEN WORSE! Help, someone please explain to me what is happening?! It's not hurting but it's numb feeling (like it's asleep). Its gotten so much bigger since yesterday and the skin feels like its going to explode its swollen so much!😣
