Ive cold/flu symptoms with past 6days, cough, stuffy nose, headache, hot and cold, body aches, some of these have eased a little as ive been taking exputex and lemsip, then uniflu tabs, the only thing thats bothering me is a pain across my chest the past 2 days its a dull pain but constant, also have pain in back, had pain in my stomach at times too and diarrhea, should I
seek a doctor or get more otc medicine?
