Get regular exercise. Do not strain when you have a bowel movement. Take a warm sitz bath several times a day. Do not put any salts in the water. Learn to life heavy objects using proper techniques, so you do not strain your back or GI system.
Prolonged use can cause inflammation and scarring.
Avoid laxatives, that can cause diarrhea and irritate the GI system. Insert petroleum jelly just inside the rectum to reduce the painful bowel movements. Aspirin and ibuprofen can irritate.
