Hi Karina, My sister bent her tailbone during labour and delivery 8 years ago with her second child and still to this day she can't sit for long periods of time. She went to the doc and to physio but all to no avail. I carried and laboured all of my babies posterior but it wasn't til I had bub number 5 that I had any trouble with my tailbone. It now pertrudes out and to the right slightly Dr told me that when everything softened it bent but didn't go back into the right position and will be permanent and I will just have to learn to live with it and in time it may lessen, or have another baby and see if it corrects, not likely. It kills somedays, particularly when I am sitting at the computer for hours doing my assignments, I use my arms to push up off the chair the pain is so severe at times. I hope yourse can be corrected,I feel your pain babe.
