I don't know what's going on but lately when I have bad pain I get dizzy and have to lay down. It seems to be when a get bad pain in the middle of my back and my muscles are real tight. It's not sharp pain but a deep aching pain like my bones are in a vise. I also get nausea and have the sensation that my spine is unstable like something is going to move the wrong way.
I don't think it's the meds because I have been on the same thing (hydrocodone plus 1/2 a Flexeril at night) for 5 years with slight increases.
