I usually get a bad reaction to bugbites, swelling, extreme itching, etc. About a week ago I woke up covered in little bite marks all over my arm, which quickly became a nasty rash. Over a week has passed & it's still very itchy, the rash has spread (mainly because of scratching) & welts. I've tried everything I can think of: ice, aloe vera, afterbite, baking soda, you name it. Hydrocortisone makes it burn & itch more, anti-itch cream doesn't work very long. Any other suggestions? I'm about to cut my arm off from the itching.
