I've had rsd 21 yrs. the first 4 yrs. I jerked almost constantly, pt, surgery , drugs didn't help. massage therapist convinced me to see a chiropractor. He used a hand activator that gently tapped neck. Shockingly I quit for hours. i went every day, then every other day for couple of mnths, finally once a month. It was painful because my other muscles hurt because they had been out of alinment for yrs. but it worked,( I rarely jerk now, sometimes muscle spasms) also made colon and bladder problems.bearable.( don't know how that worked but loved it) my leg was also shorter and a little curled and it made it better too. he retired and i used massage and reflexology but finally saw reg chiro and he keeps me going. I saw him for 6 mths before i let him touch my neck.(if tapping made me quit jerking, popping might make me start back) but it didn't ( still grosses me out when he does it.) I've been seeing him for abt 6 yrs, he even massages neck and back so ins pays for it. I know Chiro isn't for everyone but it has been a miracle for me.
