I don't get why you don't just go to a&e OP, or why you're saying you have no idea why it hurts, but are then saying you've had a very bad fall confused. If you've literally had an accident and can't use your leg, which hurts, then just go and have it looked at and x rayed so a professional can advise. It could be anything from a torn ligament, a fracture, a break, a pulled muscle, a strain- all common if you've fallen bacon
I didn't do anything of note. No accident, nothing. I can use my leg.
It can't possibly be a fracture, as I've not had a bad accident.
I think its more likely I've unwittingly twisted something with a odd move or something.
The fall I had was because I tried to bend my knee to stoop down, and suddenly it was agony again (after having been pretty comfortable, just a little sore so a very slight limp). It made me cry out. Generally its not hurting now,but I cant use it fully is all.
I think the miniscus thing sounds very plausible. I looked it up, and the inside of my knee is sore to touch prod and poke particularly the bony bit, I imagine where the top edge of the tibia is.
I did worry a lot about dvt. I have no symptoms though, other than pain on bending my knee, apart from that nothing dramatic happened to cause the pain. The fact that I can press on the bone and it hurt tells me thats where its coming from whereas dvt would be deep inside,normally, the calf muscle.
No swelling no bruising, nothing to see.
The warning is good to look out for though, shortness of breath etc.
I am thinking, like most things, will be able to heal on its own without intervention. Maybe if it goes on longer than a few weeks I should get it looked at?
