Infant circumcisions are done on a very small area. Some degree of non-perfection is inevitable. It sounds like you might have a skin adhesion, or something. They're minor mis-healings in your surgical wound, or minor mistakes in where the foreskin was removed. Don't worry...they don't really do any harm.
"I don't believe in magic. But I do believe in interpreting coincidence exactly the way you want to." -Sherman Alexie
