For about 9 mos , I have had a dull pain in my tailbone. It isn't always there, I generally notice it only if I sit on a hard surface and sit straight or leaning back - if I lean forward, it doesn't hurt at all.
Also, for the same time I've had an itchy area of skin, um, at the top of my buttcrack right below my tailbone, I haven't looked at it, but it feels like a rash or eczema almost and does itch. In fact the itching is often more noticeable than the tailbone pain...thinking they might be related.
