osteoarthritis
"Have end stage knee arthritis and am scheduled for TKR in 8 weeks. I was getting along fairly well, working 12 hour shifts in ICU, until about 3 weeks ago. The pain, stiffness and muscle spasms in my right leg became unbearable.  I could only use the word "agony" to describe how I felt. I could hardly walk and felt like I was suddenly crippled. The surgeon was only able to move up my surgical date by 10 days. I saw an ortho doc this week for a possible cortisone injection but decided not to go that route because I did not want to risk the chance of a post op infection.  The doc prescribed Diflofenac 75 mg twice a day. I am flabbergasted by the results! I have never taken any kind of pain med that actually works like this med. It's amazing!"
