question: I have had  acid reflux for almost six weeks which was made worse by steroids 4 weeks ago. I have been treated for urti with lots of antibiotics. Then one doctor said i actually was suffering from an allergy. I have a post nasal drip also but not sure if from acid reflux. Been on nexium last month hasn't really worked. Now have constant pain in sternum area I think you call it. Have lost 9 kilos in this time frame. Booked for endoscopy in one week but am worried it won't find cause. I'm worried I will never feel well again.....
