Well Kevin, it's very good to hear your alive, you seem to be quite the fighter, keep it up mate!
After thinking on what you said, and studying some anatomy, there is the chance that the glans is just "tender" without the foreskin covering it, this is why being covered with a condom would reduce the pain, the snug fit and light almost "natural" pressure, kind of a replication of the foreskin. I hope this make sense for you.
So, if you've no objection to it, and don't want to hassle with anymore medical procedures, perhaps just wearing a condom will do the trick?
I wish you well, and hope things work out for you.
