I can't breathe properly, and spent over an hour at my chiropractor's while he worked on it, trying to make my back stop spasming. My back hasn't stopped spazzing for the past 12 hours, I can't sleep, I can't breathe, and the one sneeze I've let out today nearly killed me.
The verdict? About a week of healing.
What did I do? I sat up from lying down.
