Hi, I'm a 26 year old male. My grandma died of stomach cancer recently. Well, I have felt this pain in my right side, it's not severe just a discomfort. Anyway, I got a CT scan and they just found a kidney cyst in my right kidney. So I followed up with my doctor and got an ultra sound they confirmed the 7mm kidney cyst and don't believe that it's causing my pain. At the same time when I got the CT scan they gave me a blood test and urine test which stated everything was good. I have sometimes noticed blood in my stool and narrower stools. My bowel movements haven't changed much not really constipated or having diarrhea. I still have the pain in my right side sometimes mainly only when I'm sitting it has gotten much better. I thought it was because I have started doing the treadmill but it doesn't really feel like a muscle pain. I'm just wondering if I should ask for a colonoscopy from my doctor. The pain has been going on for about a week now. I thought the CT scan would show any type of colon cancer, could be wrong though. Thank you!
