LOL! It is true that maggots eat only dead flesh, and can actually clean a wound better than can be done otherwise. Just isn't something I would want to go through though!
If you had to get rid of some dead flesh, I would bet that after one day you would get over the yuk factor. The desire to heal the problem would rule out over the alternative to undergo a lengthy treatment, even with painkillers and meds. Consider the yuk factor of having rotting flesh with you 24x7. It's amazing what the mind can overcome under duress.
