Suggest Treatment For Tailbone Pain

I fell on my tail bone awhile back, however, just recently it's been giving me pain and discomfort. It hurts whenever I'm about to sit down/get up, when I sit, and when I lay down. My tail bone area is swollen, and it hurts by just the slightest touch. The pain is getting worse each day. Do you have any idea what I have, and what I should do? Thank you.
