@dlowan,
Yes, I think so, Deb, followed by a pretty intense few days at work.
I didn't stop running around for about 7 solid days.
And I mean
serious running around.
Lesson learned: Slow down, you crazy, frenzied woman!
I am so happy not to be working today! A little more time to rest.
Thanks for your suggestions, David.
In the end I opted for gentle exercises & a heat pack.
Luckily I have a friend (who has suffered far worse back pain than I was experiencing) & she provided the advice & the heat pack.
I am feeling much improved today.
What a relief.
