For the past three days now I have been having bad stomach cramps and have had to spend at least 3 to 4 hours a day sitting on the toilet.

I have never had any stomach problems before one morning three days ago, when I awoke with this horrible stomach ache that I can't get rid of and this constant need to open my bowels, necessitating me spending longer periods sitting on the toilet.

I have not vomited and don't feel nauseous, but my stomach hurts all the time at the moment. I am not constipated and my stools are very soft and very pale, but I just have this constant desire to keep opening my bowels. I don't feel like eating a lot at the moment, but when I do I again have to go and sit on the toilet for a BM within 30 mins of eating.

Can anyone help and tell me what is wrong with my stomach? I would appreciate it as I am getting fed up with having to sit on the toilet for 30 mins at a time and also with this constant stomach ache that won't go away.

Thanks
