Bloomer Injury

I'm sitting here with a hot pack on my lower back which hurts whenever I stand up. The pain hit me in the middle of the night, approximately 2:37 a.m. when I got up with my youngest son to get him ibuprofen and Sudafed for his virus.
Within minutes I had diagnosed my lower back pain -- bloomer injury.
In my spare time, I've been helping with costumes for the fall play Little Women. Mostly I've had to take in pants, sew ribbons on collars and put velcro in place of buttons for quick changes. Then came the challenge. The four daughters in the play must have bloomers. Never mind that no one will ever see the bloomers. They help make the characters feel more authentic.
I was given an assortment of sheer white material and used bed sheets to cut bloomers from. So Wednesday morning, on my day off, I was bent over the table trying to cut around the pattern with dull scissors. My husband wandered out of bed and pushed me aside. He took over the cutting.
I moved to the armchair and the coffee table where my sewing machine was set up. I had not seen the sewing machine since we moved. As a matter of fact, this is the old sewing machine and I know that I have a newer one somewhere that I inherited from Earl's mom, but we can't find it. After two years of not running, the machine is complying, although an electrical short somewhere causes the needle not to move at all while I have my foot holding down the pedal then it will suddenly race. It's a little temperamental.
I completed one pair of bloomers while Earl cut out another pattern (winning big husband points).
Then I went about my day, grading papers, shopping at the thrift store for more costume needs, studying algebra with my 13-year-old. I was blissfully ignorant of the pending bloomer injury that had already taken place but was worming its way into my muscles.
Just as I diagnosed myself, I am also in charge of treatment. Heat. Cancelled run this morning and even called off trip to work out at the Y. I thought about going and if a weight machine hurt my back then I would stop, but since I didn't recognize the bloomer injury when it occurred, I might not recognize that a weight machine was exacerbating the problem. So I'm staying home, grading papers, and I might move the sewing maching to the dining room table so I can show those bloomers who is boss and finish the other three pairs.
