I had a Thrombosed HEmmeroid a couple of years ago so I know exactly what your going through. I was told to keep it from reoccuring keep taking Metamucil Fibre daily, exercise and watch your diet. I also took alot of baths with epsoms salts to soak the darn thing. Its gone now for me and I hope I never get another one it was so painful. I also rubbed vit e oil around the rectum to help things heal.
