HELP! ⚠️ Low back pain started at 9 weeks- remedies?!

Ladies, I am 10 weeks today and have been experiencing AWFUL back pain very very low (just barely above my butt) for at least a week. It mostly hurts when I am standing and hurts even more as I walk, to the point that I am basically limping!

Has anyone else experienced this before and what did you do to alleviate the pain?

(A little background: I have scoliosis and have dealt with low back pain a lot in the past several years. It has not been bothering me again until very recently.)
