Remember that left-sided neck pain I had a week or so ago? Well, it's been replaced by bilateral upper shoulder/lower neck stiffness and pain.
Diagnosis: trapezius stitch injury.
Yes, I made that up.
It's from sitting on the couch and stitching for hours at a time. I'm serious! I usually start around 7:30-8:00pm and I won't move until I can't see straight anymore, which is about 10:30-11:00pm. This discomfort reminds me of my University days (and nights) of studying. My posture wasn't good back then and it most certainly has only worsened over the years.
Sigh .. what to do? I'd tell my patient to stop the offending action/strain. But for me that means putting away the Hermit for a few days (a week?) and that's tantamount to telling a drug addict to stop cold turkey.
