My husband started having rash on his face and his whole body. He tried all over counter allergie medicines, didn't work. He went to the doctor, doctor gave him 3 different prescriptions 6 days ago, didn't work. He ate the same food ( I stop giving him can food or any pickle), I use the same detergen, nothing new in his daily use, no new clothes. Any idea what is happening to him? Thank you.

It sounds as though it may be an allergic reaction of sorts. Sometimes we can become allergic to things we have previously been using. Medication is one that we can become allergic to all of the sudden.
