i don't feel it is psychological at all, it is as if my heart is just going to give out ... i have blood pressure problems but i take meds for that. i take neurontin. i have rsd left lower leg and now right foot and my hands have either rsd or reynauds ... the doc is not sure. i'm almost 12 years with this and am weaker and have spread somewhat but still get around just very slow going. i do everything in pieces.
