I am suffering from muscular pain,in my right leg.I m taking Celebrex,One capsule a day,after food.Last this was very painful,and I had trouble sleeping,also had a bit of arthritic pain,in my left arm. I ve no swelling,in the right leg.I called in a national doctor,but he was useless.Some time ago,I fell over,where my leg went all stiff,and the ulstra sound said it was muscular.This is exactly the same.How do I get rid of the pain. It seems a lot better now,but its at night,when it starts,and it stops me from sleeping.Can you help me.Thank you.Denise Merton
