In pain

I have a sore right knee and I have been molly-coddling it along. I have a doctor's appointment the Wednesday before I go to China for a cortisone injection. What happened today? My knee clicked backwards and left me in excruciating pain. A visit to the doctor and I have it strapped up, a pair of crutches, three lots of tablets and instruction to not get out of bed all weekend!

Just what I don't need right now with having to take my mother to visit my dad and my husband leaving. Hopefully my sons will help me out
