Hi, I can understand your concern for the spreading itchy rash on chest, back, legs and stomach in your husband. I can make a possibility of Allergic dermatitis. In Allergic dermatitis there are eruptions along with moderate itching and in more aggravated cases there is appearance of more redness which persist for more than multiple of days. The only precaution you must follow is not to touch, pinch pop or squeeze any of them otherwise it can get infected and can cause complications. You can apply medium potency steroid cream application of fluticasone cream. You can additional take antihistamine Ben Chat Doctor. If the things are not getting better than can meet a dermatologist for further guidance. Take care.
