Don’t just do the scent training, it’s worthless for those of us who just can’t smell it. Call your big hospital and ask for the pain management clinic. If you talk with someone in that department, ask about the Stellate Ganglion Block injection. Look it up. I don’t know where you live, but I live in a suburb of Chicago and have gone to Northwestern Hospital in the city. I know that Cleveland Clinic is also doing it. Good luck! Don’t stop!
