Thank you Emily. My thoughts are with you. I am in agony today but this info from you was helpful ...'Sympathetic Blockage (Phentolamine)'. A prior PM doc had suggested that I should consider an infusion of lidocaine ... ketamine ... and phentolamine ... meds each pushed separately. I did not know what that last med was for ... now I know more about phentolamine.

We all need to help bring more awareness to this terrible crps/rsd pain condition so researchers will work towards a cure.
Thanks again.
