Hematoma can be the case.
Detailed Answer:
Hello!
Thank you for the query.
Generally such symptoms in this area can be caused by some inflammatory process. No redness or swelling must be visible. Sometimes pain is the only sign. Its because muscle in this area is ample so an inflammation can be inside it. Not visible from the outside.
Mentioned scooter ride can be an injury. Such injury can cause small veins rupture and blood appearance in the soft tissues. It is called hematoma. Large hematoma wont disappear by itself and sooner or later starts to hurt.
The pain has nothing to do with the anus or digestive tract.
I suggest you to have soft tissues ultrasound to make sure there is no hematoma present.
Hope this will help. Feel free to ask further questions.
Regards.
Does this give you a better indication of what it can be?
