Naproxen
"I am 51 yrs old with advanced Osteoarthritis in both hips, and on the surgery wait list to have THR.  Naproxen is quite amazing for me at controlling OA pain.  So far I only take it when I have upcoming situations where I will need to walk alot.  For these situations I'll take Naproxen 1-2 days in advance, 2 x 500mg tablet daily.  It makes a huge difference.  If I didn't worry about stomach or intestine damage I would take it continually.  Other days, I try to get by with low doses of ibuprofen."
