I know that waits for surgery are not uncommon in the Canadian health care system but I also have to assume that if your AN were in any way endangering your health or life, it would move you to the top of the 'list'. This being the case, I concur with Jan's advice to let the doctors office know that your symptoms are getting worse. If brushed off, send a registered letter to the doctor explaining the problem.
This kind of situation with a Canadian resident tends to confirm my reservations regarding 'universal' health care that some are eager to see implemented in the U.S. If 'everyone is covered', often that 'coverage' leaves a lot to be desired.
That aside, I hope and pray that you can have your necessary surgery soon and that it will alliviate your symptoms and generally have a positive outcome. Please keep us informed.
