Have you injured yourself in that area? I only ask because I have RSD/CRPS, a severe, chronic pain syndrome. Have you gone to a Pain Management Specialist? The one pain we all share is the burning pain, and your stabbing pain is also one we have. It can be triggered by an injury, minor surgery, in rare cases, it can occur spontaneously. I also have Fibromyalgia, but burning pain is not one of the symptoms of Fibromyalgia, just our RSD/CRPS.
