I have had a rash for about 3 to 4 weeks now it is on the back and side of my neck, in my armpits, inside of my elbows, forearms, under my breasts, lower abdomen, groin, and back of knees. It is extremely itchy and seems to bother me worse at night. I have also been experiencing foot and leg cramps on a daily basis, sore throat, congestion, and heartburn. I went to see my doctor and she said it was most likely from my detergent so I bought dye free allergy free detergent and have not used or eaten anything different and the rash isnt getting any better.
