Re: Mama's with nose piercing....
Get a pro to look at it. Iodized salt is FINE. Not preferred, but not harmful, certainly.
Lots of people get little bumps, usually they go away after some time. If it is red, painful, or oozing that is infection, but I don't think you have any of that.
What material is your jewelry? Some can cause irritation and bumps. You may need to try titanium or glass. Not SS. And not all steel is the same, it has to be 316L to be high grade.
I would say it is caused by irritation from either poorly fitting jewelry which is rubbing, or irritation from the material of the jewelry.
The world would be so boring if everyone were the same...
