Left shin pain increased overnight, it's on the inside and feels the same as when I've had it before. At rest it's fine, hopping on one leg is not. If that's not grounds to not run then I don't know what is. Plan at the moment is to assume that this is going to get worse with running, i.e. finally get myself a bike like I've kept telling myself to do but this time for real, strength and conditioning, and see what happens. With just my input so far and dealing with this in April first year and in March second year (huh, weird), the first time I switched to the watt bike for two-three weeks and it sorted itself out. Last time we went for the more measured approach. Just frustrating really, but unless this is a freaky, didn't-sleep-right accident, which it probably isn't, gonna need to back off.
