My experience is similar in that the bone discomfort, all in my right leg, is worse at night and it helps to get up and move around. Walking seems to disrupt it though an arthritic knee flare up can complicate that, too. Both are issues since having my first and only Reclast infusion 18 months ago. These episodes sometimes come out of the blue, lasting a week or several and go away just as quickly. Best wishes to all to come through these challenges as they can be life altering.
