I was experience same symptoms since my rsd started ,so far my flare ups well calm down a little bit with my scs implant,I only supposed to had my right foot and ankle affected according with my pm dr but in reality my whole body suffers when flare ups appear . Stress is a big no no when you have flare ups,get more intense ,spasm, neck pain back pain running every where also happen but some dr prefer to ignore it,in my case,but my body feels the effects , with the scs is been more in control lately but to get to this point I was and still have side effects from the first surgery,gabapentin supposed to calm the nerves,lidoderm patches num your skin, flexeril or baclofe.n help with the spasm neck pain,that combo work for me but is not accurate all the times ,some times no matter how much meds or increase the scs frequent no even that works,I also still getting use to ,rds/crps is so hard to understand ,hope you get better soon and you can be able to find a combo of medications that work for you,scs works but depend of your life style,if you are to active might not be appropriate for you,you need to slowdown with the scs unit implanted,is a nightmare some times to be honest,works but you ended with more side effects,mentally and psychically ,blessing and hope you find a way to control your flare ups soon,keep the faith is a long road to walk,so ,try to do and practice how to relax yourself in those days,relax and relief your stress is the only thing that really works,medications help but remember ,mentally we are tired,and that gets us sooner or later,try to relax and soon you will be able to control the flare ups,good luck and blessing to you,from jesika
