Hi I was wondering if anyone could give me some advice. I have had stomach pains for 16 weeks now and in this time I have had diarrhea for the last 10 weeks. I can't eat or drink anything without feeling sick and being sick a lot. I've lost a stone and a half in weight and feel weak and tired a lot where I can't sleep properly and now I have a lump I presume is a haemaroid appear at the opening of my anus (sorry to be graphic). My stomach also has a burning sensation where the pain is. I have also pain at the top of my abdomen. I have spoken to my GP who has referred me to hospital for tests. The first are a CT Colonoscopy and a CT Abdo Scan. Blood tests and stool samples. I can't stop thinking these are going to turn out to be cancer and I'm getting so upset. Has anyone else had these and been ok or am I right to be worried. I would like to hear other people's experiences please help.
