Tailbone Injury

Somehow,  in my otherwise cookie cutter birth, I managed to severely injure my tailbone. It is not broken but it's excruciating to even sit or drive. My son is now 7 weeks and it has not improved, even with the coccyx pilot or osteopath and chiropractic therapies. Has anyone else had this experience? I've been told it takes a very long time to heal but not sure how long that might be.
