Extreme pelvic pain

I am 36weeks5days and last night we went to L&D because I was in soo much pain I was crying when I shuffled my feet in a sad attempt to walk. They said there's nothing that can be done and basically I just have to suck it up.

My question is, has anyone else experienced this and what relieved your pain? I can't walk, my husband is doing 100% of everything today and I would just love some advice. I am on the verge of attempting to crawl but I'm afraid I won't be able to get out of the floor!
