i am getting quite worried now because i am having terrible stoma...

Hello, having read your post I would urge you to go straight to your doctor as your symptoms should not be left. Whatever the cause, your symptoms need to be checked out as they could be life threatening, and the sooner you take action the better, I don't want to scare you but doing something about it is better than worrying and hoping the problem will go away. I really hope that there is a simple explanation for your discomfort and that you are soon much better. All the very best to you.
