Hello, my left hand and arm get tingly when I'm sitting in certain positions, or when I'm standing and walking. It started out with an uncomfortable pain in my left shoulderblade; I have been seeing a chiropractor who has been adjusting my back and neck, and then having me get massaged. He is adamant that he can fix it but says it will take time. The massage therapist has been concentrating on my neck, shoulder and back and that no longer feels tight, however my shoulder is very sore on the bone and in the muscles around it, and my hand and arm numbness are not going away. Can you help me figure out if I should keep going to the chiropractor, or if I should get an exray?
