Hey Boo Boo.. ( I just LOVE that name )
Yes, hemrroids can bleed A LOT. My dad had a lot of problems with them. He had bleeding & they did some surgery that helped. I don't know what pain meds you were on but if it was vicodin or anything like it it can cause a lot of bowel problems. That's why I can't take them.
Hope you get this situation under control and give that GP a peice of your mind.. heck you can give him a peice of my mind too . since I'm not using most of it these days LOL!!
Feel better..
