"I was given some samples of Celebrex from my physician for wrist and hand pain.  After I took the second capsule of 200 mg, I awoke in the night with an extremely bad headache, had the chills, aching muscles, runny nose and a dry hacking cough.  I stopped taking the pills, but as my symptoms persisted, I believed I had the flu.  Three weeks later, I again tried Celebrex and on the second day of taking the pills, I was again stricken with chills, a headache, nausea and the runny nose.  These symptoms have stayed with me for the past three days.  "
