Brief Answer: Please read detailed answer below Detailed Answer: Hi XXXX, Thanks for writing in to us. I suppose that you fell on your buttocks and there is pain and swelling at the site of the tail bone (coccyx). The tail bone is made up of fused segments of small bones and is the last bone in the spinal column. Falling on the tail bone can cause small dislocation and rarely a fracture. Some people experience pain especially while sitting but you should not get worried. A X ray of the coccyx is done in most cases. Even if there is fracture of the coccyx there is no surgical treatment required for it. You may avoid sitting on your tailbone for a while. You can use a doughnut shaped pillow and feel comfortable. You can gently apply ice pack and pain reliever ointment on the swelling. Hope your query is answered. Do write back if you have any doubts. Regards, Dr,Vivek
