Hi.I am 20 years old.male.i was on a high protein diet before.for the past year and a half i have been experiencing some stomach problems like irregular bowel movements,water coming up to my throat and sometimes excessive gas due to indigestion maybe.the stools are very sticky and loosely formed and are very difficult to deficate completely.during and after passing stools(whenever they are sticky,loose and not deficating properly)i would have severe anus burning sensation but the sensation goes away as soon as i deficate completely.lately i have been taking senna leaves(kayam churan)to help clear out the stools and it is working but as soon as i stop taking it the same problems comes back.i have had several blood tests for the liver,blood cell count,electrolytes,thyroid etc and also had a ultrasonography but everything came back normal.i dont have any pains in the stomach or any bleeding through the anus.i am quite sure the burning sensation isnt because of piles.doctors prescribed several medicines but none of them seems to work.please help.
