"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."
