I had a mini worry about number 10 too. I had an unfortunate incident with an incorrectly placed labial piercing that went through my erectile tissue. Because of the 'do not remove' mantra I sat on it (or rather, I couldn't sit on anything) for 3 days, whilst it bled and bled and encrusted with blood. I was terrified, but in the mid 90's doctors were clueless about piercings and I was miles from the piercer by then. For this reason I'd prefer the advice to be simpler, less scary, and say something like:

"If you're having problems with a piercing then removing it might not solve the problem and could even make it worse. Removing jewellry from a new or problem piercing can leave bacteria inside it. If you are having problems with a piercing then go to your piercer and ask for help. If you have no other choice or you have already removed the jewellry then flush the wound through with your cleaning salt and water solution - keep using the solution to clean the area until the wound heals."
