When I was about 7 years old, I was sliding down a hill in the winter and landed on my tailbone. The pain was excruciating but it went away after a few days. Years later, at the age of 16, I started to experience severe pain when sitting at school. It would feel irritated at all times so I went to see an orthopaedic surgeon. He said nothing was wrong with my X-ray so he referred me to another doctor. That doctor ordered an MRI. Before the MRI, after feeling my coccyx over my skin with his hand, he suggested it may be bent at a 90 degree angle but needed an MRI to see. Results from the MRI came in and it in fact showed my coccyx being bent at 90 degree angle which wasn't normal. He booked my surgery and I got a my coccyx removed three months later at the age of 17 turning 18. He said the pain would last about 6 weeks.
It has been four years since my surgery and I will be 22 this year. The pain has never gone away. It just would get irritated when driving for long periods of time, or if I was on my time of the month (strange I know) and if I had to sit during school a lot.
A few days ago, I got an excruciating pain in my coccyx area where it was removed. It stings all day and hurts even when I sleep. The pain has gotten to the point where it hurts to bend and I'm using my tailbone pillow again for first time in four years. I may visit a doctor soon to see what's going on because at my age, I shouldn't have this much pain when I sit (because I sit all the time).
