Ohhhh, my poor knee

A few years back my knee started acting up. I was still tap dancing at the time and had to take several weeks off since it was hardly able to hold my weight..poor knee. Anyhow this past year it has been bad on and off. I went to regular doctor, x-rays, etc. No sign of arthritus, no broken bones..yet still hurting like crazy. Well the hubby said call for a surgeon referrel, so I finally did. My appt. is Monday. Well, this morning I was in my room and I picked Rosie up to bring her downstairs. There is one step from my room into the hall landing. I stepped and heard the worst noise in my knee ever! It hurt so bad I thought I would pass out..still holding Rosie! Luckily I have a chair right next to the doorway and I sat in it and tried to calm myself down. Oh, the freaking pain. I managed to get downstairs, took Advil, and waited. At 8:30 I decide I would make the trip to work and stay as long as I could since I will probably not be working on Monday....I stayed until 3:30...omg. Came home iced my knee on and off. Tried to rest on sofa, but the girls would not cooperate and were jumping all over me. So, my right knee is all swollen and who knows what else and now I sit and wait for Monday....blah!
