I just got back from a beach vacation, but since my last day in the ocean, my back has been extremely itchy. On my last day I did get a little burned, but it was better the next day. I also have a few scratches, but it is due to scratching burned skin. My back gets so itchy that I can't do anything but sit with an ice pack and wait for it to pass. I have also had problems sleeping. Currently I have tried taking Benadryl which didn't help. I also have tried putting on aloe, aloe with lidocaine, Eucerin lotion for itch relief, and anti itch lotion. Please help, I don't know what else to try.
