I am 52 yrs old, and a polio survivor. I had a fall over a year ago and scratched my leg, which quickly turned in to leg ulcers. the pain can be very bad some times, my doc has precribed Zydol 100mg, Lyrica 150mg, and cata flam 50mg twice a day. it helps keep the pain under control. But i worry about becoming addicted to any or all of these drugs. Does anyone have any answers please.
