Back pain

Unbearable back pain, I can’t stop crying because of it. No contractions, just an intense pain on my right back side (I think because the baby is ROA). Any good remedies? I’ve tried massage, warm shower and Tylenol, nothing is working. If I sit kind of leaning forward it helps for a few minutes but then it comes back again. I’ll see my chiropractor Monday, but I still need to survive today and tomorrow, have no idea how I’ll sleep because laying down causes the most intense pain. Thanks for the help!
