"i noticed a lot of people on here giving up after only a week or so.i have been on celebrex for years and at different times i would stop for a week or 2 immediately i would start going downhill. celebrex needs to build up in your system the more time you take it the more it helps.should give it at least a month.i was on heavy pain meds for years now all i take is celebrex i have severe neck and back problems and severe arthritis.celebrex is a miracle drug for me without the side effects of heavy pian meds.thank you for celebrex it has changed my life"
