Has anyone given birth unmedicated with sciatica pain?

I have really horrible sciatica pain in my right leg that radiates from my butt cheek down to my knee.

If I’m in a bad position for too long, if flares up and I have to walk the pain off for a few minutes.

I can’t sit on anything too soft because if I sink in (like a foam mattress pad) I end up activating the pain.

My husband has had to carry me to the living room it gets so bad.

This pain popped up with my pregnancy. My belly is too big even though the rest of me looks like I haven’t gained anything so my my baby’s weight and my belly is pressing on my sciatic nerve.

I wanted to give birth unmedicated, if possible, but it seems like an epidural is one of the only ways to avoid and relieve the pain during labor and delivery.

Anyone else have sciatica pain and made it through unmedicated or without an epidural?
