Hi ! Many times undiagnosed amebiasis is a common cause of such distressing symptoms. I would advise you to go for a routine stool test for ova and cyst, and if positive, discuss with your family physician for a course of anti amebic which will relieve your symptoms. Some physician prescribe anti amebic drugs even when the stool test report is negative with dramatic results. Apart from this, I would suggest you to take some kind of probiotic in your diet regularly along with lots of vegetables and enough of liquids. Also go for regular exercises within your own limits. If you take all these precautions, then I am hopeful that it won t get worse as you age. Thank you and good luck.
