Pot for pain after Prostatectomy

Short answer, It Works!
A friend, who gave me my ride home from surgery, gave me a little cannabis. I had heard that it could be used for pain, but I never believed it. Have grown up in the 70s, I am no stranger to it, but I always thought that the talk of using it for pain was just to push for legalization. After my first night home, 2nd day after surgery, I was in a lot of pain and watching the clock to get to my next 4 hour oxy dose. I had fallen asleep mid after noon (side affect) and woke up 5 hours after my last pill and I was really hurting. Not liking the side effects of the oxy and worried about constipation, I gave it a try. To my total surprise it worked better than the narcotics. I could tell the pain was still there but I could just ignore it and had no need for the oxy. I did take it for a few more nights because it helped me sleep through the night, but that was it.
