35F pop & pain in low back; can’t get up

I’m currently on hold to talk to my PCP nurse. Posting in the meantime.

This morning I was completely fine up until around 9:30 AM when I got up from the couch. As I started walking I noticed some sciatica pain that came out of nowhere. It steadily got worse until my husband had to help me lay down. About an hour ago I sneezed and felt a large pop in my lower back (and more excruciating pain). I’ve been laying ever since and now cannot get up due to excruciating pain.

What do I do?
