I have the same problem with my tail bone.It irratated more when I sit on soft cushions.The problem seems to be that my bottom sinks in the cushion and my tail bone does not and it is not comfortable.I find if I put a boardto sit it does not bother as much. The next time I see my Dr.I am going to suggest they remove some of my tail bone so there will be clearance when I sit. This maybe the answer I HOPE.
