Somebody help

Timea • Mother 2, pregnant with number 3!! It's been a long journey but I'm anxious to meet my third son, James jr.
I'm having extreme back pain ( not labor ) but back its so bad I can barely move without a sharp pain running through my back. Idk if I pulled a muscle or if this baby is just too much to carry now . I went to 39th week checkup yesterday my OB said I'm being induced Monday but I don't think I'll make that long with these pains ? I've tried Tylenol ( per my OB ), I've tried warm baths and even exercise to loosen up my back. Nothing is working .. Please help me ??
