Hi guys...Ever since I was little I've had chronic pain that comes upon having a bowel movement. I am a 15 year old female, and I am incredibly pain tolerant, but this pain is terrible enough to make me dry heave and cry. It comes at random times, and is only when I am having a bowel movements..I have researched high and low to find answers, and my mom doesn't think it's anything serious. The pain level is so incredibly high that I actually get to the point of dry heaving...I'm only allergic to Kiwi, and I stay far away from that, so it's not an allergic reaction..I have no idea what's causing it, but it's absolutely miserable and lasts for about 15-20 minutes, forcing me to continue using the bathroom even if I don't have to go anymore. Help would be seriously appreciated.
