Hi I am 18 years old, and 4 days ago I woke up and felt my hands burning, and they were also red and swollen. The next day I started to get blisters in between my fingers that resembled a burn, so I put my hand in cold water which didn t do anything. I went to the doctor yesterday, but they didn t know whether it was an allergic reaction, spider bite, or anything else. I m getting discoloration on my face, and I don t know what to do. All the doctor gave me was a benadryl shot.
