Hi
Welcome to the MedHelp forum!
There are two possibilities that you must rule out. One is fissures and the other is hemorrhoids. Fissures can be very painful. There are local rectal analgesic gels available which you can apply before passing stool. Keep the stool soft by increasing fibers and fluids in diet and taking stool softeners.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
It seems that you are pushing too hard and also you are probably not drinking enough water for proper elimination. Pushing too hard can cause the hemmoroids to swell which causes pain. Try adding more fiber and water to your diet.
Best of luck
Are you pushing to hard? if so just relax
