Hi, I am someone who had this done, I had no idea what to expect and I refused meds for the procedure, big mistake. It’s basically done with a scope similar to what they use for colonoscopy but shorter in length, the doctor locates the hemorrhoid and then ties some surgical thread around it. That’s the whole procedure, the hemorrhoid shrinks because the blood flow is tied off and eventually the dried tissue will come out at some point but you won’t notice it. I found the aftermath discomfort more tolerable than the pain from the hemorrhoids before the treatment but I definitely wouldn’t do that again unless I’m asleep.
