Take anti-inflammatory drug like motrin
Thanks for your query.
From description it seems to be soft tissue injury
over tailbone. You need an x-ray to rule out any bony injury.
Do icing over affected area. You can take anti-inflammatory drug like motrin to reduce pain and inflammation.
Avoid sitting over hard surface and rest well.
I do hope that you have found something helpful and I will be glad to answer any further query.
