Ok now this one's freaking me... A couple of weeks ago I was asleep, and suddenly woken up by a horrible, strange sensation in my right knee. It's difficult to describe. It wasn't PAIN as such... It wasn't even numbness... It was just some terrible and distinct feeling of wrong... Stiffness maybe? Pressure? Mild numbness? Increasing in the knee and starting to radiate around it. I was terrified, I thought I had a blood clot or something like that, I tried moving about and rubbing it and plenty of things, and then over the next half hour or so the feeling gradually faded away.
Now, that scared me, but I thought it was a one off. ... Until just now. Once again, led on my back, asleep and fine, when suddenly woken up by this horrible knee sensation. Except this time it's my LEFT knee. I can feel it now, and I still don't know how to describe the sensation despite how very distinct it is. It's really scaring me though. I have no idea what could be causing this problem. If anyone could tell me anything at all I'd really appreciate it. Thanks.
