Talk to Gastroenterologist on Intestinal And Rectum Pain

I was having loose stools every week since last few months and constipation alternately. And i have pain in lower abdomen every day before passing stool. Yesterday i saw a drop of blood also when i wiped with tissue to confirm. And since yesterday i am having rectal pain and backache. I am also having itching and burning sensation around anus.
