Had my baby 2 weeks ago, she was back to back and delivered with mid cavity forceps after I had been pushing for an hour. Since then I've had sharp lower back pain when sitting, walking etc which doesn't seem to be gong away, and is very localised around my tailbone. I'm wondering if I've maybe fractured it? I've been discharged from the midwife but I don't know if it's something I should bother the GP with yet.
