I have no idea what I did to myself (probably too vigorous cleaning in preparation for a holiday guest), but I have somehow injured my SC joint --the place that the collar bone attaches to the sternum. The left joint area is swollen to about three times the size of the other, and I have never experienced such pain. I woke up during the night hurting when the Lortab I have left over from a hip injury wore off. I got online to see if I could identify the culprit and figured out the problem. It is tender all the time, but when I pressed lightly on the area to try and determine the extent of the swelling, I nearly passed out. I ended up in the bathroom, hunched over the sink, nauseated from the pain. Fortunately that passed, but I'm curious if anyone else has had this problem. My husband had to pull me out of bed this morning because it hurts for me to do it myself. This stuff always happens to me right before a weekend or holiday -- when my docs are out of touch and there will be several days before I can be seen. As long as I relax I'll muddle through, but as I get older, I'm finding parts of my body I never knew existed!!!
