I have been experiencing intense pain in my tailbone region since last night.  I did not fall down or anything out of the ordinary.  It hurts at all times no matter what position I am in.  Is this something that I can treat at home or do I need to go to the ER?
Without an actual examination, I cannot give specific medical advice on your particular health, but sitting on a hard surface, strains, minor trauma can cause minor pain. Rest, keeping off of the area, baths in warm water are all often helpful
