Why does my back hurt so badly?
So Tuesday night I changed my rear brake pads, and it required me to contort myself a little up under the car ... so I didn't think much of it when I woke up with a sore back on Wednesday morning. Pain just on the upper left side of the back, so I figure I pulled a back muscle or something.
On Thursday night, I took a muscle relaxer before I went to bed, and when I woke up Friday morning it was even worse. I noticed that the pain had spread to my chest muscles as well. Really bad muscle pull I guess. When I woke up this morning, it was hurting as badly as it had the day before, and the day before that.
When I got out of the shower this morning, I noticed the rash on my chest. Didn't take much 'Googling' to figure out what it was.
