It seems I may have somehow damaged my right knee, although I have no idea how. It's been hideously painful for about a week, and I really need to see a doctor soon. I can bend it without a problem, but straightening up is agony. Plus it often feels like it's about to give way under me. Going up and downstairs (unavoidable where I live) is excruciating. The poor dog's cheesed off because he's been no further than the back garden today. I've lain around on my bed all day, but can't afford the luxury of lolling around any longer. Hate aches and pains - they're so annoying. Ugh, bah humbug, etc.
