Sorry about no responses to your posts, however, you may have problems that others simply have no experience with. We are not medical professionals.
If you already had a hemmoroid, it is possible for it to become inflammed due to rectal exam. If you have constipation problems after surgery, that may be the cause of a flare up.
If you have success in the past using creams, etc. then I would just wait and see if it will go back down. If it does not, then see a doctor. It is my understanding that hemmorids will flare up, settle down, flare up, settle down for years and years before having to resort to surgical removal.
Don't worry about the no responses, my questions are very seldom responded to either, but, I do learn a lot from others and like to share with others if I can be of help.
