Painful body pains. Need advice

amy • 2 kids,1 angel baby,#3 on the way married 11 years

I want to be induced at 37 weeks my body is in so much pain I can't lay down, I can't sit for long. When I sleep I have to sleep sitting up I'm just in pain all the time no matter what I do I honestly can't take it no more. This is my 4th baby I never felt this much pain with the rest, I was induced with my son at 37 weeks cause he was getting too big. I'm hoping my doctor will let me be induced. If my dr says no please is there anything I can do for the pain. Oh nd I'm 34 weeks an 3 days
