Blisters on hands symptoms and conditions

Have been to the ER twice - both times on death's door. Blood pressure dropped dangerously low so I ended up in ICU both times. Liver function was elevated. Blisters on hands and face. Can't sleep at night. Feel exhausted. Got so sick that all major organs were shutting down. Doctor's did not realize that I might have an allergic reaction to this drug until I mentioned it the 2nd time in the hospital.
