My friend is experiencing a stabbing, burning knot in between his shoulder blades. It hurts him more when he moves; movement is unavoidable for him because he is constantly using his arms because he has no use of his legs. We went to the hospital and all they did was prescribe him Percocet, which does nothing for it. Thankfully the pain is not related to the metal rods in his back... does anyone know what we can do to relieve some of his pain?
