question: My mom is a post cancer patient, of this last winter she completed her treatments for oral cancer, had rad and chemo and no surgery..... She has had some complications recently with an outbreak in what appears to be blisters patches of hives on the centre back and upper arms armpits, ect, I believe it s all upper body,.. But she has been taking extra strength Tylenol, for headaches and general malaise,.. And she appears feverish, an achy ear and side of head,... Back aches as well, joints ect, also.... Could exposure to sunlight while taking these pills do that? She is reluctant to seek any treatment and always tries to avoid it at best of times... Advice?
