i am a 38 year old male 180 lbs. very active and work out 4-5 times a week, recently for like 10-12days I've felt a sharp pinching pain in my upper rectum or end of my large intestine area (not sure can't exactly pin point) when I have gas only I feel this... I've been very gasey of late and can feel a gas bubble travel around to where just before I pass the gas it gives me this sharp pain... if I don't release and push the gas out but hold it in I will feel the pain again, no pain what so ever when I pass stool so it makes me feel like the gas bubble hits a spot and gets stuck? makes no sense to me what causes the pain but it is very concerning... could it be a tear in my intestine?
