In the past 10 years, I was twice laid low for months on end due to a pinched nerve.
Man! is it nasty!
Could not even sleep lying down - had to sleep in a chair.
Working out can aggravate the condition as the back and shoulder muscles when they bulk up tend to yank/squeeze the nerve, thus causing it to flair up inside the nerve canal in the spine - that's where it gets "pinched."
So I laid off working out for over a year.
Went back to the gym the other day thinking MAYBE, just maybe, it's OK now.
I didn't do a whole lot - just stretching and small free weights.
But that night I could feel a little tightness in the neck, shoulder, and the back: symptomatic of the nerve getting yanked or "squeezed" a bit.
SIGH.
Alrighty then, I guess I'll just turn into putty.
Better a functioning putty than a Hercules bound to a chair.
Well, there is Yoga, I suppose.
