If you have not done a parasite program I think that would be good to do. Another thing would be to rule out Celiac Disease and other gluten sensitivities/intolerances. If you can't afford the tests you could follow a strict gluten free diet for at least 3 months. I used the Soecific Carbohydrate diet and there are others online. See http://www.celiac.com
for more information.
Telman wrote several message about abdominal pain and gallstone pain. One is a chart listing the problems and where the pains occur. In another message he wrote about people who have sharp bends in their intestine which hangs up the intestinal contents. Often this pain occurs after exercise.
For Candida I've found Pau d'arco quite effective. It is necessary to keep from being constipated and I use a combination of magnesium oxide taken daily, magnesium laxatives to clear out the large intestine and herbal laxatives to clear out the small intestine. You should have a bowel movement within an hour after eating a meal. so for most people 3 bms a day would be optimal. I've also found salt water flushes to be helpful.
Keep doing LFs, H. Clark wrote that a person need to get out about 3000 stones before changing to yearly flushing.
Hope this helps.
