Broken tailbone? And how to sleep/get comfortable?

So early today I slipped and fell down the stairs on my tailbone. I have been in constant pain all day and can't find a comfy position. (Laying down, sitting, standing up) I have prescription extra strength ibouprofin, took it, it didn't help. I have tried going to sleep I wedged pillows under my back and legs, still hurts. I tried ice and heat all day. I can't find a way to sleep, if anyone has a way please tell me. Also, could my coccyx be broken, or one of my lumbar vertebrae be broken or fractured? I know there is not much a doctor can do for a broken coccyx but should I go anyway, don't want to waste the money?
