In May 2013 I was admitted to hospital for appendicitis.
Prior to the operation, my surgeon was concerned that my symptoms didn't match up 100% with appendicitis, so he scheduled me for a CT scan instead.
Three years earlier I had passed a large volume of blood in the toilet bowl after going to the toilet. I went to a GP who said not to worry about it unless it happened again. As it didn't happen again I didn't go back to him.
