im 25 weeks and 5 days pregnant and i have terrible pain in my lower back. on one side. what could it be?

And I also was throwing up from the pain, so that could be what you're experiencing! Doctor can prescribe flexiril but I was very uncomfortable taking it so I broke them in half and only took a half of one for a few days, it helped dramatically!

I had sciatica around 20 weeks and it was the worst thing ever, like debilitating pain! Thank god it didn't last more than a couple weeks.

it hurts so bad i throw up:(

Sciatica 😕 I have it too.
