Me too, I get it down both legs, my physio said it is where the sciatic nerve pain, hits the bundles of nerves in each fibro pressure point, in each n every muscle.
I have these points deep tissue massaged. Its ok for about a week, then its back again, however I've notices it is less severe x

Happened to me that first sent me to the doctor have you figured out if you have a vitamin deficiency or not I had a deficiency in B12 and vitamin D and it's certainly helped once my once my levels got back to normal.

I get that too--seems the muscle wears out easily. I use Ibuprophen for it because nothing else seems to help

I take magnesium in the evening and normally feel good if it’s not raining or cloudy that day.

Thank you for sharing Crystal and Dixie. Also all Fibro warriors for your love, lots of prayers for you 🙏🙏🙏🙏
