i need to read more about them but these would be temporary nerve blocks to find out where the pain is coming from, i believe they'd wear out in a few hours. what gave me the idea was when i went to my dentist and got a novocaine injection on my left side, my neck pain went away for a few hours.
i have a whiplash type injury to my brachial plexus on both sides, i did to myself from my neck muscles being SO weak. my entire neck and shoulder used to be really lax, especially my shoulder. i LONG for those days, now all my muscles are gridlocked, i think from irritating the nerves so much. my scm muscle in particular used to be grid locked, i felt like i was choking.
the fun NEVER ends and the more i think about it, the more my head spins bc my body is pretty asymmetrical i feel..maybe my right side being so lax (my shoulder is winged) would effect my left side, maybe my tmj is causing my neck pain, maybe my elevated shoulder is causing my neck pain, maybe my loosey goosey pelvis is messing up my entire torso, and on and on *sigh*
