No processed meats, red meat, pork, fried foods, cheese or mushrooms. Chicken breast
and salmon are very good and organic yogurt because the enzymes are really good. No cold drinks and avoid beer. When it's hurting put a hot compress on the area, it might help, it helped me. Also try to minimize stress.
I'm now taking omega 3, 6 and 9, vitamin c ascorbates with msm, selenium, mastic gum to protect and heal the gi tract, and aloe vera to help with digestion and acid control.
