I fell pain on my legs on my legs , i used voltaren (diclofenac) crem but now is not working, can i take osteocare?

You need to see a do: Doctor to be evaluated. Leg pain is very non specific. Did you see a doctor that prescribed the first cream. I would go back to them and tell them it does not work.

Osteocare: I would not take osteocare without supervision by a physician. This is not a generalized pain reliever and does contain calcium. Research is showing mixed results on calcium supplementation lately and physicians are increasingly becoming concerned that it may accelerate coronary artery disease. Bottom line: ask your doctor first. There may be better and safer alternatives.
