I recently injured my neck/shoulder, and have just started going to physical therapy. The current thinking is that I have a chronic condition, perhaps degenerative, that is not serious but has been worsening over the years and needs some life adjustments to slowly turn around: posture, stretching, general awareness of how I am moving - that sort of thing.
My office mate has an accupressure device she keeps on a hook, which she encouraged me to use. I used it on a Friday, felt much better Saturday, but far worse on Sunday. I suspect I actually did slight damage with it. I was encouraged to use it by a lot of folks at the hospital, a lot of them nurses, and often with the same explanation: "You've probably got some kind of knot...that could really help you break whatever knot you've got there...I had a knot and I found that pressure really helped...your shoulders look hunched like you've got a knot up there..."
Except it wasn't a knot. What is it with jumping to the conclusion that it's a knot these days? How did this become the go-to explanation?
