About a month ago I treated an elderly gentleman who came in limping with an osteoarthritic knee. I asked him to rate his pain level from 0 to 10, with 0 being no pain and 10 being excruciating pain, and he replied "it's a ten! It's like a constant toothache!" After I treated him the pain went down to a 2, but he looked at me skeptically and asked "how long is this going to last?" I told him it could last a day, a week, a month, or the pain could be gone for good. Results are individual. He arched his bushy eyebrows and said "we'll see."
I saw him in passing today and asked him how his knee was doing. He said it was good that we ran into each other because he wanted another "magic treatment." I then asked him how long the pain relief lasted after he last saw me, and he said three weeks.
What pill can do that?
Update July 28th: The gentleman informs me that he hasn't needed any painkillers since the first treatment. He says he has almost forgotten that he had a knee problem, his knee feels that normal.
Update April 24th, 2016: Still no pain and the knee was fine all winter.
