Had terrible anterior lower leg cramping last night, lasted for approx 10minutes. This is the 2nd time this week. wondering if there is anything I can do to lower the possibility of this happing again. I have a very bad knee on that leg, and actually need a knee replacement, but at only 40 we are trying to hold off, I did have a steroid injection in this leg 10days ago, and have had wonderful relief from it.
