Hi, thanks for writing to HCM.
Based on the description, I suspect that you could have suffered a soft tissue
hematoma along with injuring the coccyx (tail bone).
An xray of the sacrum is needed to rule out any bony injury.
The general management guidelines are as follows -
* Apply heat or ice to the affected area
* Sit on a doughnut-shaped pillow or wedge cushion
* Lean forward while sitting down
* Take over-the-counter pain relievers, such as acetaminophen
(Tylenol), ibuprofen (Advil)
involving strengthening of pelvic area muscles , stimulation with ultrasound
Hope this information is helpful. Good day
