I don't know how I managed to do this but I have ankle pain which also seems to relfect to my mid shins and I also have shin pain.
It hurts to walk but more then any impact pain is the pain I get from lifting up each foot (called 'dorsiflexing') and then lowering my foot back down again. The areas that hurt are the front of my ankle when my foot is pointed or moving downwards and the middle of my shin, dead on straight in the middle (not to one side) when I lift or raise my foot. It does wear off a bit when I run but its straight back again when I stop and doesn't ease off after sleeping well or walking around, only running or cycling.
I have no idea why! I am assuming its to do with the weather, that I am colder then normal and so starting out I maybe should have spent longer warming up- I notice that (I run a lot on a treadmill) where I used to just hit the treadmill running from the word 'go' and build up speed, after about 3-4 mins I am warm enough to begin sweating, this evening it took 20 mins just to feel warm enough to take off my jumper- in a gym!! And then a further 10 more mins (30 in total) to just begin sweating so its obvious my body requires more time to get the circulation going but can't help thinking that as much as I am wondering about this, its maybe not the problem: I get no other pains in my body, say quads, upper body or even back, last year I was given a diagnosis of cartilidge damage in my knees which apparently is osteoarthritis yet even my knees feel better them my ankles!
