Possible causes of pain when sitting on the buttocks after a fall include epidermal contusion, localized muscle tissue injury, sacrococcygeal fracture or bone fracture.
1. The fall caused epidermal contusion, resulting in localized swelling, oozing blood, the injury heals and scabs when the buttocks sit down will cause the scabbed area to produce pain.
2. When the local muscle tissue is injured, part of the muscle tissue is broken, and bleeding occurs within the muscle, and when you sit down, it will press and stimulate the injured muscle tissue, and pain will occur.
3. Sacrococcygeal fracture or bone fracture will lead to localized swelling and pain. When sitting down, the fractured or broken part of the bone will feel the pressure and produce pain.
There may be other reasons why your buttocks hurt when you sit down after a fall. It is recommended that you go to the hospital in time to find out the cause and treat the cause.
