I was diagnosed in October. I had shoulder surgery in April and the swelling and pain never went away. I don't know how you feel about going into the city but I am going to Columbia. I commute from the NY/NJ border into the city. My surgeon referred me after thinking there was some nerve related issue inspite of a negative EMG and when I went, I had my diagnosis pretty immediately along with my treatment. So far I have had 2 stellate ganglion blocks with a few hours of relief with the first one. I see Dr. Visco and Dr. Smith. I am happy with both so far. Great bedside manner!!!
