32 weeks tomorrow severe tailbone pain

So went to bed last night was fine. Woke up this morning with severe tailbone pain and went in for my normally scheduled Chiropractic appointment. She was worried I might be in labor so she called my OB to get me in. He checked on baby and said that it sounds like I bruised my tailbone some how while sleeping. Now I'm on Tylenol and heating pad all weekend. Is there anything else I can do? I have to go to my Fiance's mother's birthday dinner tomorrow night.
