How long have you had this? Do you think it is from your digestive system? Do you have digestive symptoms? Is the pain worse a few hours after eating? Sometimes people with candida problems produce plenty of gas, and at times if the gas builds up, it can be quite painful. Perhaps certain foods might trigger this? Another thought is that some supplement you are taking might be irritating your digestive system. Are you taking an iron supplement? Certain forms of irom are very irritating to the digestive system. Can you think of any supplements that you added soon before this problem started?
