Oooh, Janet! I'm coming out there! Don't you cry anymore.
That pain sounds a lot like sciatica. That's a bad pain. You can't sit, stand or lay down. I had it once and it went away and has never come back. It was from lifting my youngest granddaughter too much I think. Have you been lifting or doing anything different that you could stop doing?
One day at a time with the weight. like Gina said, baby steps.
I love you.
