I have pain. I have frequent headaches, back pain, fibromyalgia,etc.. Yesterday I began to feel bad with these types of pain. I can usually take a muscle relaxer, norco pain med and feel better. Yesterday and today it is different, the pain keeps coming back within a couple of hours. It is very unusual for the pain meds to not work. I keep goimg back to bed with pain med, ice pack, tens unit. I am somewhat concerned.Thank yoy
