Now I use a compounded cream prescribed by my PM nurse practitioner. It has about seven different things in it. I know 2 of the ingredients are
ketamine and lidocaine but I can't remember the rest. (This also runs around $200.) I find this works a bit better than the Voltaren.
The lidoderm patch I cut to fit my hand, where the worst of my pain is, but I also use it whole on my hip, where I also have extreme arthritis pain.
I'd ask your doctor about a prescription cream.
