Bruise on penis, short ferenulum

i just got bruise on my penis due to short frenulum after some gentle masturbation.
I have also surgery planned in few months to cut the frenulum.
will the bruise just fade away or should I do something with it?

This does not look like a bruise - it looks more like a blood bleb trapped underneath the top layers of skin
It will reduce in size and eventually fade in the next 2 to 3 weeks
