I have had chronic muscle spasms in my back since 1988. MRIs show very slight disc herniation L5, S1. I work out regularly as well and as consistently as possible with this condition. Chiropractor regularly. Have done physical therapy, Egoscue, yoga - you name it. I'm in a big spasm again for no reason. Can anybody recommend anything here? I'm trying so hard not to go into depression and discouragement.
