I have severe knee pain from traumatic arthritis from the army. I have taken 10/325 hydrocodone for 2 years now. The Doctor just switched me to 5/325 oxycodone since the hydro no longer helped, the oxy is not helping either. The VA is very hesitant to prescribe opioids or benzo's is there any thing stronger that I can fight the VA to get? I'm also can't take Dilaudid.
