I Have Had 3 Major Back Surgeries, A Broken Back,

I have had 3 major back surgeries, a broken back, fibromyalgia, a dislocated collar bone, etc.... I take oxycodone, soma, lyrica, motrin, Tylenol, l-tyrosine, and a few other meds, supplements. I am currently in quite a lot of pain while waiting on a new pain mgmt. doctor. Can I take valerian root to help me get some sleep?
