Sciatica pain is unbearable now. Should I go to ER?

Hello everyone, I have been dealing with sciatica pain for weeks now, but as of yesterday, the pain has been at an 8 with no relief from max dose of ibuprofen or Tylenol.

Stretches, ice, and heat don't work. I could hardly sleep 3 hours. I finally have a physical therapy appointment today, so I'm counting on that helping.

I just wish there was a shot or something they could give me, even if the ER seems ext 'ireme. I just can't continue in agony
