Without going into detail I have cervical spine issues. I have had epidural injections in my neck but they have done little to help with the rock hard muscles in my upper back and shoulder. The aching, burning, pain radiates into my side, on my upper arm, and into my hand. Oddly enough there has never been pain in my fore arm. On Thursday I had 5 steroid injections into that rock hard muscle and the pain in my hand stopped instantly. Also, the burning and aching in my back, shoulder, and torso has stopped. I'm thrilled and keeping my fingers crossed. Just wanted all of you to know that this seems to be working for me. Happy Thanksgiving!!
