Penile trauma, fracture or hematoma are all possible.
The treatment as well as recovery time would depend on the severity of the damage. If it is just a bruise, convservative therapy like warm paks a non-steroidals can help.
However, before treating this, I would consider imaging studies. This can start with a penile ultrasound and can get more detailed with CT scans and MRIs.
I would discuss these options with your personal physician.
Followup with your personal physician is essential.
