I'm trying to get back into playing shape, and I've spent most of the time on the elliptical. With treadmills and running outside, I've had a slight bit of pain in my lower legs (inner side of the tibia, front side of my leg). I have a shin sleeve and that helps a bit, but I was wondering if there's anything I can do to make sure it doesn't get worse. Obviously, I know I can stretch more (which I'm doing now), and then even more general things such as making sure I'm hydrated. Any other thoughts? Thanks in advance.
