Back that thang up

So yesterday morning, I was on my way out the door to work. I leaned over to grab my keys from the table, and BAM! my back went out. People think your back going out is like a snap, like something is dislocating. In the movies, there is always a big cracking sound when someone's back goes out. But for me, I have a back spasm. Usually just one. Every single muscle in your back squeezes soooo tight, like a fist clenching, and then just let's go, completely. It's like when they let go, they have given up working. "Yep, we're tired of carrying you around all day, so we're gonna take some time off. Here are some incredibly painful nerve endings to replace us." At that point all I can do is grab my cell phone and my bottle of pills and slump to the floor.
This time I started crying, nearly hysterically. I could tell it was going to be bad. Last week I'd had a tiny spasm, which scared me, but didn't actually hurt me. That should have been my first clue.
So I lay on the floor, while Joe did what he could to help me. I got a few more spasms, which is very bad, and cried more, but mostly because I did NOT want to call out of work. The head of my department was not going to be there in the morning, I had gone home sick (very sick) just the week before, and I knew this was not a good day to call out.
However, due to my inability to even stand up, I had to. I then proceeded to take muscle relaxers until I passed out for a few hours. Sometimes when my back goes out, I lose entire days without meaning to.
Back at work today, I can't sit for more than 3 or 4 minutes at a time. My brain is foggy because I have to take more drugs to keep my back from spasming even more. And, what's worse, the one guy who actually was here yesterday morning didn't notice there was a satellite feed to do. My boss, who should step in at times like these, didn't notice either. Technically, it's his fault, but try telling him that. Now we're going to have to have another "meeting." Ugh.
