Thanks for the reply mate, im going to see the doctor on tuesday. I hope i dont need any operations or anything like that done. I just want this gone! its affecting my life!
First off, stop freaking out. Anxiety is like a megaphone for all your symptoms. (I know, it sound like a pithy thing to say, but 'tis true.)
As for your symptoms, they could be a very, VERY large number of things based on what you describe, so instead of asking here I recommend you go see a doctor. Sounds to me like you may have some gastritis, which would explain the acid pain. Problems caused by digestion at that end could also be causing a few issues in the rest of your body.
FYI: I've had the same exact symptoms you've mentioned. In my case it was a gallbladder attack (because I was eating not so healthy stuff like Chinese food and spicy goodies from India), compounded by GERD, which caused the gastritis and esophagitis. Everything was pretty well inflamed in there and I was having all sorts of burning, nasty pains doing both 1 and 2, but once I got the acid under control, everything else eventually calmed down (most everything within a couple of weeks).
Of course, I'm not a doctor and I've never met you so this isn't exactly what you'd call a diagnosis. But what you have doesn't sound all that serious yet. Still, you have to get to a doctor to make sure whatever it is it's taken care of. Even if it isn't serious (and it chances are it isn't) left untreated it could very well become.
