Actually, I forgot to mention that I do suffer from a ganglion cyst in my right wrist, but I'm fairly certain it is due to strain from having played tennis for 30 years and working daily from a pc for over 20 years, and not a consequence of periodontal issues (even though I suspected that might have been the case up until a few months ago). (The cyst now is mostly gone after having taken a "course" of copper aspirinate internally).
