osteoarthritis
"I take this for significant pain caused by osteoarthritis.  Before my GP put me on it I was losing every morning to barely being able to walk on my knee due to the pain.  Started seeing results in less than 24 hours.  I was prescribed another medicine with it to prevent side effects, and some other pain killers so sometimes a bit ashamed of the combination, but for the first time in years I am almost entirely pain free all day every day."
