I am a 53 year old Asian male. 5 8 170lbs, Non-smoker, Non-drinker, HIV +, 3 cardiac stents recently, have had idiopathic acute pancreatitis circa 1999, nephrolithiasis on and off, BPH, HTN. I have intermittent lower abdominal cramps (pain 8). It is temporarily relieved by defecation. Then it returns and I run back to the bathroom. This continues throughout the day, by evening it subsides. Now I am on week 2. I had this same episode in 2011, surprisingly activated charcoal helped. Is it a parasitic suspect?
