As many already said,baclofen works well for muscle spasm and also with spine issues ,flexeril is mostly for muscle spasm,like Tessa said,call the dr office ,there is always a dr on call ,he /she will be able to recommend something to keep you out of pain,also warm water works ,or a warm pad place on your upper back and neck,hope that helps a little bit and hope you get better soon, try to relax as well , from Jesika
