I've been having a really star ge lain in my right knee. Its just below my knee cap, kind of my shin? It hurts so bad when bending my knee or after a period of immobility. I've had it for about six weeks. Some days it's worst then others and some days my knee will be giving me super sharp achey pains when just resting. Its not hot to touch, it's not swollen, it's not tender to touch. Its like a stiff painful feeling mostly on movement. My GP said just leave it and let it heal. I don't even recall banging it or anything. It just started hurting one day. Do s anyone know what it could be? I am overweight, very overweight. I know that's probably not helping and I am trying to lose weight. But if it was directly weight related surely it would be painful in both knees and not just one? Anyone had similar issues? And know what it could be? I have anxiety and have made up all sorts of dreadful illnesses in my head.
