Health, the bottom line is that you say that nose rings are “probably assur” and I think that they are probably muttar (but disgusting). Let’s blayb by a teiku.
P.S. This machlokes only applies to nose and extra ear piercings (which are also revolting). Piercing other body parts, which has become somewhat popular in the general population, is, in my opinion, vadai assur as they are clearly related to pritzus.
