Hi, thanks for writing to HCM. As per your description, I suspect that you might have injured the coccyx (tail bone piece) resulting in COCCYDYNIA. An xray of the sacrum will show up if there is any bony injury. An MRI scan is necessary to know the amount of soft tissue damage in that area. The general recommendations for coccydynia are as follows - * Sit completely upright with proper posture — keeping your back firmly against the chair, knees level with your hips, feet flat on the floor and shoulders relaxed * Take over-the-counter pain relievers, such as acetaminophen (Tylenol), ibuprofen (Advil) * Apply heat or ice to the affected area * Lean forward while sitting down * Sit on a doughnut-shaped pillow or wedge (V-shaped) cushion *Physical therapy involving strengthening of pelvic area muscles , stimulation with ultrasound therapy If all the above measures fail to provide relief from pain, a local steroid injection may be helpful. Hope this information is helpful. Good day
