sciatica?

Maxx
I've been having terrible back pain everyday when I come home from work. It starts while I'm at work (doing laundry at a hotel) I'm on my feet all day but sit down when I can. When I come home and try to relax I can't get back up. The pain is unbearable! I can hardly walk and it's worse when I lay on my back. Doctor said earlier on that it's the sciatic nerve and to try therapy. It's not helping. After I've been sitting down or sleeping I can hardly walk,sit or stand 😩 the other day it made me literally fall trying to get out of bed it hurt so bad
