Yesterday morning my back was still really stiff and sore, but I was mobile. I made it downstairs and then...sneezed. My back seized up, and I was laid up all day long. Occassionally it would start to feel better, but then I would move wrong or try to do something and mess it up again. The only way I could get anywhere reasonably comfortably was by crawling or having my husband hold me up, so that my back didn't have to support my weight. Getting ready for bed really messed it up, and I could hardly sleep for quite a while.
This morning I felt better but was afraid of making it worse again. The stress alone caused more tension. I called the Dr's office and got an appt for 1pm. Finally around 11am I dared stand up..and it worked! Briefly--I got some food and ate and had to lie down again. But I've been able to be more mobile and upright over the course of the day. It's almost hurts more to sit than to stand, except I quickly tire from standing.
The Dr said it was a lumbar sprain (strain?). So I'm supposed to avoid high impact activities for a while, rest, and slowly work back into running. Ah, fun times. I hate this.
