Hydroxyzine
"I was prescribed hydroxyzine for severe itch. No doctors have a clue why I have these severe itching events. But I also have other problems. I have spinal stenosis and using fentanyl 50mcg/hr every 3 days. Still recovering from colon cancer surgery. Was just diagnosed with arthritis of my hip. There are days I can not walk even with the fentanyl. Started taking hydroxyzine only when I itch and it took a few days to put 2 and 2 together and realized my back and hip almost totally stopped hurting and was able to walk without cane or walker.  Next time that I took hydroxyzine for itch, same thing, I could walk without pain. I haven't told doctor yet, wonder what he will say and if this drug helps me why didn't he give me hydroxyzine sooner?"
