Hi , I have bilateral thoracic outlet syndrome where I only had 1/3 arm and hand function left in dominant hand surgically fixed this fall waiting until neck fusion I just had c 3-5 is healed to do left side later- slowly getting out back together after accident. Still having neck pain in TOS part of neck but does anyone get twitching of arms and legs this is new. Since acdf. Also hard to sleep in hard collar afraid it will flex or bend my neck funny I have to wear it 24/7 for 10-12 weeks. Does that seem overly paranoid- I know it can't really flex in the hard collar! Does anyone experience a hard "line" where there incision is. Hats off to the posterior approach patients I don't know how you can bear to have the hard collar touching your incision all the time. Bless us all and fast healing and answers to everyone. Thanks to all for I out I have bee lurking on this forum for over a year and it has provided me much advice courage and answered many scary questions that I have had.
