Hi, I am a 28 yr old female, and have had several injuries to my back over the years. I have fractured my sacral/coccyx area several times through slips and hard falls during runway modeling when I was a teen, and the only tx I received was a crappy doughnut pillow and nothing regarding follow ups. Now that I am older and married, my husband commented on a hard 3-4 inch hard lump in my L5 S1 area. I have known of it for years, and always disregarded my severe back pain. It looks as though my bone has grown back weird. Having a frank breech baby via C section 3 years ago didn t help me, my OB GYN stated that my baby was making my tailbone injury worse as she got bigger in the womb. Also, I recently strained my lower back above the L5 area, and just came back from the hospital after receiving injections and prescriptions with an order for a follow up with my PCP in 3 days. I will definitely be going. Besides the new injury, which I will continue treating, I was curious about this large, hard lump in my sacral area. What could it be? I have always hurt in that area, and am constantly stretching it and attempting to pop my back in the morning after I wake up. Should I make sure that I get more than just a simple X ray? I work in healthcare, and am well aware that X rays only show so much of an injury. Thanks, Hurting Mommy
