Hi. For the last 4 months i have been having mostly green diarrhea or green stools. I get bad stomach cramps some days or sharp pains. I get headaches often (2-3 times a week).

I have been to the doctor many times and they just tell me its a bug because its going around at the moment ( not that ive seen anyone else with it, nor would i have a bug for 4 months ). I'm getting rather fed up with the doctors because i am kinda worried it could be something serious.

I know the poo isn't green because of supplements or eating too much iron because i do not take supplements. I do not eat too much green vegetables nor do i drink junky drinks with lots of coloring in them. I have a good balanced diet (or as balanced as i can get it anyway).

Oh and btw im a 21 year old male if that helps.

Thanks very much in advance!
