A few years after vertarae C6 and C7 fusion along with plate and screws I started having chronic pain in my neck once more. The doc prescribed to me 100 doses of 30mg roxicodone. The medicine worked great. Upon completion of the script I quit cold turkey. My withdrawal was somewhat sever. I experienced cold sweats, anxiety, felt sick and pain. Canâ??t imagine the withdrawal from years of use. In the end I received a cortisone injection which has worked for 15yrs but now the pain has been flaring up once more.
