Actually, I was going to mention about the anesthesia side effects too. That will actually take longer to clear your system than the procedure. As for the size of the cyst, you should feel immediate relief but don't take that as a sign that you can do more than you should. The most important time is the week following the procedure. That is when most of the base healing will take place. If you are a very good little girl and follow directions, you will back on the bike in no time. Good luck with the procedure and let us know how you are doing.
