I had to go to Bowen Therapy this week as I had neck problems, and told him about my sore butt, and he said I wasn't in alignment. Very common during pregnancy and birth. I think my problem happened during birth. I birthed on my back as the midwife had to move my cervix out of the way, and DD was born within minutes of doing that, so no time to get up.
Since going to Bowen Therapy, I've had a lot less pain down there. I can actually sit on the lounge without fear!
