Hi Undergroundbarbi
It's quite understandable that you're feeling really stressed about this, waiting for results is always a hellish experience.
I'm sorry, I haven't had a polyp removed so can't advise on the bleeding, but I had surgery to do so but there was no polyp there! I waiting about 9 weeks for the results of the biopsy so I know what the waiting game is like.
Why don't you telephone the consultant's secretary and just explain how you are feeling. Say you'd been told you wouldn't need to be seen again and that their recent letter has therefore made you really anxious. I feel sure they won't give you results over the phone, or at least the secretary won't, but they may agree to send some info to your GP so they can discuss it with you. You may not be successful but it's worth a try and they may be able to reassure you in some way.
I wish you well.
