If it is not a fissure or hemmie, it might be food-related (as odd as that sounds). I had this problem for many years (it was almost unbearable at times!) and found that it was related to what I was drinking. In particular, I had to give up my beloved coffee, but doing so really alleviated the problem. Here is a site that talks about food-related pruritus ani: http://www.fascrs.org/patients/conditions/pruritus_ani/
This might not solve your son's issues but it is worth thinking about.
Also, before I figured out it was food related, my doctor gave me some cream--mometasone furoate--that helped a lot. It is not good for long-term use because it is a steroid, but it provided some much needed relief.
I hope he finds relief for this super annoying problem!

Did you just say that drinking coffee made your butt itch? Wow.
