I too have this problem. I have had an abnormal tailbone for many years and am only 24yo. I cannot sit on hard surfaces or sit for long periods of time. I also cannot be standing for too long as this will cause pain. In recent years I have suffered with agonising pains within the pelvic area and they tend to flare up far worse when I sit or lay for too long. I dont want to whinge to my GP as Im currently trying to figure out other problems with my body. I cannot find any info that may help in figuring out what could be wrong.
DO YOU HAVE EXTREME PAIN AND EDEMA LIKE POUCH IN YOUR TAIL BONE- DID YOUR DR SAY THIS WAS ODD TO HAVE - i MIGHT HAVE THIS I HURT AND CANT NOT LAY OR SIT ON TAILBONE IT GET WORSE AS TIME GOES BY.
I have the exact same tailbone. It has been causing significant pain the last 6 months but have had it since birth without many problems. Went to the doctor a couple of days ago & had x-ray which shows the tailbone turned outward like a small tail. I am being referred to an orthopedic surgeon & will update you with what I learn.
