Sometimes I think all the special this or that doctors need to find problems to justify their existence or so you can't sue one day for negligence. I'm on an anti-doctor roll right now, With PPMS DMDS I've tried don't work, Besides MS I'm pretty healthy, have no pain, I'm 54, leave me alone. My PCP is always there for me if needed. I've got better things to do. I've also heard too many stories of "cures" resulting in things worse than the ailment.
