How Can Buttock Soreness Caused By Injury Be Treated?

Hi, may I answer your health queries right now ? Please type your query here...I fell quite heavily 2 weeks ago on my bum. I was playing field hockey and slipped. I landed straight on my bum and then fell back and hit my head. I had a sore neck for a few days but my bum is still very sore when I sit or lie down.
