Hello Grace, sorry to hear you're suffering like this because I have had whiplash before. It is something that hurts real bad and all that therapy fells good until about a couple hrs later when it wears off. I now suffer from what called Cervical Dystonia which is severe muscles of the neck. I have such bad spasms that they have now left me permanently disabled. I was just wondering if you take any kind of muscle relaxers? I know that the Oxy is not really going to help that much with muscle spasms that I know of. I was also wondering if anyone had suggested having Botox injections to help with the muscle spasms? I hope you can find some relief soon because I live with severe muscle spasms all the time especially when the weather changes or I over use my arm or do any kind of lifting over my head.
