WHAT TO EXPECT POST PROCEDURE
You are expected to have post procedure anal pressure. This can last for a few days. For control of pressure, use over the counter Tylenol 325mg, 1-2 tabs every 8 hours as needed, for the first several days. Most patients DO NOT experience pain. Just in case you have pain, your health care provider may prescribe pain control medication If you are one of the few patients who requires pain control medication make sure to bring the rest of your prescription bottle to your follow up appointments Spotting of blood may occur for the first few days after your procedure. Delayed bleeding can occur, usually 1-2 weeks post procedure, when the tissue heals and the scabs from the procedure site start to shed. This is expected
