And what causes it. Have been ( imho wrongly diagnosed with Sciatica for years), and have recently started with tailbone pain which gets significantly worse mainly when I'm in my office cha)it ( sat down for up to an hour and try to walk around between appointments if I can). Any ideas whether it's age ,( 52f) related / back related , whether others have had it and if it went away and what can I use to help relieve/ reduce it.
Thanks
