UPDATE - SURGERY on my lump/bump in my Penis Shaft.

i underwent a minor surgery to remove the sebaceous cyst.
the surgery looks like this now.

my question is:
how long is the healing process?
it looks inflamed or swolleb, will this heal like a normal wound?
will this flatten? i am just worried that when it heals and dries up, it will cause a bump again on my penis shaft.

thanks!

the urologist advised to leave it alone. he only gave a small pack of bacitracin. can i also put some wound healing cream?
