Went to doc with an isolated specific pain left hip area which hurts when pressed sometimes but not always. Sometimes have need to rush to loo and empty bowel but then feel great. Always had "dodgy" tum in times of stress!  I/She thinks poss diverticulitis but recommended CA125 test which came back 37. She said only slightly raised as normal is 35. I was also on my period at the time and have since read that can raise the levels. Now waiting for ultrasound. Reading the posts my pain is very specific and not like many describe. Am worried. But then feel reassured by your posts!  Confused.
