Re: Scars on penis? Very sore.
He needs to get a second opinion. Doctors are far too quick to recommend surgery, for things which can be solved by simpler means. Find a conservative doctor, who acknowledges the value of him keeping his foreskin.
First, he needs to find out if this is a persistent yeast infection, or something else.
Once the infection is over, he could try a prescription of betamethasone cream, to thin the skin. He could get a speculum, and insert it into the tip of his foreskin, and stretch it that way. If none of these things worked, a nick in the foreskin should free it.
