Yessir, I Had Back Surgery Over A Year Ago And

Yessir, I had back surgery over a year ago and still live with moderate to severe back pain. My pain management Dr. has me on Hydrodocone 10-325 every 4 hours and diazepam as needed (I limit it's use because of the drowsiness),I was wondering if the Soma or Vanadom(carisoprodol) could help me reduce the hydrocodone I'm having to take, as I'm afraid I've developed a tolerance for it and sure don't want to overdo it.
Thanks much for any and all info you could give me Dr. Rynne
