Limping after one month on Fosamax. After two months pain was so severe in left hip and leg that I could not climb up stairs leading with left leg. Pain upon getting into minivan,had to pull my leg up by my pant leg. Also upon getting into bed I had to pull my leg up with my pajama leg and then when attempting to lay down to sleep had worse pain in my left hip. Went off Fosamax and after three months am getting considerably more mobile with less pain. Told my doctor about it and refused to take it for osteopenia.
