I have had inflammation of the pubic bone, symphysis and attachments. It is called osteitis pubis. The inflammation showed up on a bone scan. I had a low level of pain for a long time that I only noticed when I would actually touch the pubic bone. It was very tender. Silly me, I thought that everyone had that and never mentioned it to anyone. By the time it got extremely acute and painful, the pain extended all the way around back to my 'sit bones'. I had to do part of my bone scan sitting down so that they could get a picture of that.
I still have a low level of the inflammation. It never entirely goes away. Mine is complicated by having hypermobility and a leg length discrepancy, which contribute to the problem quite a bit.
My pain has never really referred into the vagina, but I suppose it could. Is your pubic bone tender to the touch?
