How's it going now Ali? I'm really sorry to read about your knee. You seem to know what to do in regards to the RSD aspect of things. What did your physiotherapist or your mom say? Did you see a doctor about it since it gave out? I really hope things don't get worse for you. You have certainly been through enough!

I would think that your muscles and everything just aren't used to too much. Work it slowly but keep it moving, like you know to do. If you think the swelling is related to the fall and your mom thinks it worthwhile, not to risk further injury to the nerves in your leg, to put a bit of ice near the swelling and rest with elevation. It should calm down in a day or so. If it doesn't I would really start to look at it from an RSD point of view and ask the physiotherapist about it.

Try to look up. Talk to you soon. TC J
