I was given Celebrex years ago, but had to stop taking it because it was doing things with my white blood cells. My present Doc now put me back on it, 100mg caps twice a day, it works like a cure from heaven. But I am worried about this blood thing, and reading about all the side effects, is like reading Chinese. I am 70 years old, have no other ailments than this OA and now in the hands RA. I have tried just about every other drug on the market, but none have worked. Edith Bell
