Friday night we went to a football game. Saturday I woke up to the most intense itching on my scalp, hands and lower buttocks. I was miserable! Took Benadryl on Sunday and that helped with the itching. This morning I wake up to intense itching on m hands! and swollen hands and a swollen bottom lip. Is this an allergy? Should I go to the Dr or will it go away on its own? I have never had anything like this before. I dont take any medications and I am healthy.
