Lately my back has been freezing up, from middle of my back in an upside triangle accross my shoulders and neck. Feels like Im hunching my shoulders and cant relax them. Its just awfull,pain and stiffness. It takes 2 darvacet and a soma to start to get it to relax . Once lasted 2 days.Some days it doesnt freeze but always feels like it could at any moment. A new symptom of this DD for me.
