R Torso, Lower Back Pain
2013-02-10 – 2013-02-20
Grade: 3
A moderate Lumbar Sprain/Strain. In this case probably caused by bending/twisting, likely fixing the washing machine or getting an armload of firewood with a long XC ski possible contributing. Second one in a couple years and taking a week or so to recover.
