I'm 17 years old and have recently been experiencing these like, shooting pains going from my left side to my stomach. When i try to sleep it is really uncomfortable and no matter which side i try sleeping on the pain is there :( i have been feeling sick every morning and getting chills. A few days ago I started trembling really bad, as I am now while writing this. I have tried all sorts of different medication and nothing seems to work. I can't eat or drink without feeling I'm going to throw it back up. I am constantly gaining or losing weight, even though i'm barely eating :( I am also sitting GCSE exams at the moment and so far, I know I have failed at least 2, due to rushing them to get out of the room as quick as I can. Standing and sitting down are both extremely uncomfortable, so I am in constant discomfort. Can anyone help??
