Stuck shed - do I bother removing it?

[Lolo76]

refusing food, stuck sheds... something's wrong with him. i didn't really mean your husbandry, rather, i meant treat the issue causing the problem, rather than the problem (stuck shed) itself.

Definitely not my husbandry, since all 29 snakes are housed in the same conditions - and most eat & shed perfectly. This particular snake has a tendency to fast for 2-4 months in the fall, according to Skiploder who used to own him... so I'm guessing it's a combination of his yearly fast, combined with the stress from trying to get the stuck shed. He still has a bit left under his chin, btw, which I'm leaving until he sheds again. Everything else seems fine with his health & behavior, so hopefully it's nothing underlying that I haven't figured out.

But since you're suspicious of an "issue causing the problem," what do you think it might be? And how would you suggest taking care of that? I don't think it calls for a vet at this point, as he seems perfectly normal otherwise... my herp vet charges an arm & a leg, so I'm hesitant to run him to a doctor for no apparent reason. Since I wouldn't be able to pinpoint an issue, she'd probably just end up running $500-1000 worth of tests and saying "dunno."
