Muscle relaxers & pregnancy?

Anyone been on flexeril or something equivalent while pregnant?

I’m 10w4d and basically temporarily ruined my back. I have no idea how but out of the blue I stopped being able to straighten myself out, was falling/getting stuck on the toilet, literally at one point last night had to crawl on my needs from the bed to the bathroom bc my husband wasn’t home. It was really bad.

So I went to the ER today and since the part of my back where I can’t bend is the very low end, aka very close to the baby, they didn’t want to do any imaging just yet bc there’s no way to protect baby.

They said it’s likely either a slipped disk or some type of muscle strain and gave me a one dose steroid and send me home with a script for 10mg flexeril 3x daily for the next 4 days. I was loopy fell asleep woke up and tried to eat and threw up everywhere. But even after just one strong dose I’m more mobile.

Just seeing if anyone else has taken this or something similar when pregnant?

On the plus they did a super quick look to check baby and doc said he/she is a “leap frog” and Had a healthy heart rate of 176
