Okay thanks for any help. For over ten days my sister who is 74, is having severe pain that appears to be in her lower stomach and it radiates to the back. Very Painful. She had a CT Scan normal. All along they had thought she may have had diverticulitis and treated as such with nausea meds and pain meds. Appt to see a Gastroenterologist is being made with a colonoscopy to follow. With so much pain I am concerned there may be a large growth in her colon that has possibly spread. Any clinical advise would be appreciated. She is diabetic, but has lost 59 lbs. in the last year, She said it was easy..and that concerns me too. Thank You. Sorry I thought this was free information. Guess I didn t pay enough attention what this consisted of.
