Thank you for all the information,
It can be urethritis.
Injury or infection can be possible.
Injury usually heals up within a few days.
Infection should be checked.
I would advise to consult doctor.
Swab test, urine exam can be done.
Neosporin cream can be tried till you see doctor.
Take more fluid.
Good urine flow can help in urinary infection.
I hope this information helps.
If there’s anything else I can do, please let me know.
