Hi folks! While I'm not expecting a diagnosis over the web, I wonder if anyone could shed some light: In september I started getting an irritating twinge, when walking, on the top part of my shin, on the inside (medial, I think that is), just below my knee. Gradually it has worsened when I walk, now it's largely moved to the back of my knee and can get quite bad when I walk. My leg feels a little wobbly at times, and my leg feels slightly stiff, eg I can'g bend it fully, and if I have to kneel I do it VERY carefully as it hurts.The amount of walking I do isn't excessive. It was bad the other day when I was at a couple of airports and had to walk from one terminal to another (massive distances) and a 10-15 minute walk in town, each way. I was really hobbling badly by the end of the day. When i take my weight off it it's fine, and mostly improves overnight, then worsens again if I walk. There is no sign of any swelling and the area does not feel hot or anything. Today, when I haven't walked as much, it feels a bit better.I haven't had any kind of recent injuries. Has anyone got the foggies what could be causing this?
