While tingling in hands and feet are better rash is worse.  I now have a flat red rash on legs and arms.  It stings when it touches my clothing.  I cant get into see my doctor for another week.  I agree it is not from radiation but I dont know where its coming from.   Last night it seemed better but this morning it was red and painful again. I am not using any new products except a possible change in dryer sheets but I switched to a fragrance free one.
Hello, Painful rash on legs and arms could be due to exposure to something you are allergic to, scabies or contact dermatitis. You can take oral antihistamines, levocetrizine for relief. You can apply HY Chat Doctor.  Take care of your hygiene. Wear cotton clothes. If you do not get relieved than you are suggested to get yourself examined by a dermatologist to rule out scabies, psoriasis, contact dermatitis, etc. Cold compress & oatmeal baths or baths with antibacterial soap are effective to give relief. Hope I have answered your query. Let me know if I can assist you further. Take care
