Hi, I'm panicking a lot here, doctor just rang and told me I need to go for a camera as they have found microscopic blood in my poo. I also had various blood tests for alsorts but he said they're ok. I initially went to the doctor because of dizziness and virus symptoms which have now gone. Is the blood in poo serious? I've got health anxiety and at the moment t can hardly catch my breath since he rang me. I will be referred within 2 weeks.
