Are your methods suitable for pain stemming from a whiplash injury? I have extremely tight neck and shoulder muscles from a car accident a few years ago, causing neck pain and more recently jaw and facial nerve pain. When muscles are chronically rigid, should I still try (gently) doing the stretching exercises? I'm afraid of causing more spasm, but i've tried everything else with no luck....massage, acupuncture, heat etc. The area is just EXTREMELY sensitive and very hyper-reactive.
