Is allergy feeling in throat mouth nose ears body. itching. associated with steven johnson syndrome? please, thank you.

No: You are more likely to have pain with Steven Johnson. Your problem is more likely from allergy such as allergic rhinitis (which however does not involve the body) or less likely an allergic reaction to foods. You would be very ill if you have Steven Johnson

No: It is quite common to have itchy sensations with allergy. With Stevens-Johnson syndrome there are painful ulceration like canker sores and swollen membranes in the mouth and lips.
