hi, i have had problems with my digestion for about 5 months now, i am at university and i constantly feel ill, i have gone to see the doctor and they have done blood tests, but nothing obvious has appeared. in the end they put my problems down to anxiety or stress.

my problem with this is that it doesnt help me out, i dont believe that it is stress or anxiety.

my recent symptoms are hot feeling in my stomach/back of neck, lots of wind and gas(farts) that smells alot, i also get a strange contracting feeling around my bladder when burping at the moment which is very weird.

i am at a loss of what to do, this is really getting to me as it does stop my life to an extend and i constantly feel misrable because of it

any ideas??
