Sciatica Pain and Relief

Looking for recommendations on relief for sciatica pain. It started a week or so ago, I am almost 21 weeks now. I work long shifts on my feet as a veterinary technician and my sciatica, mainly on the right side, has been acting up a lot. It makes standing, walking, sitting very uncomfortable which then makes my pelvic floor feel super comfortable.

My doctor recommended a belly binder, Tylenol and OMT to try to get some relief. I didn’t have it when I was pregnant with my daughter. Just looking for recommendations on belly binders or other ways to get some relief!
