Retainer for surgery

Sixth month old nose piercing with slight irritation bump.

I need to change out my stud and put in a nonmetal retainer. Wondering if anyone has suggestions on shape or material that would be best for a newer piercing short term?

Age: 6 months

Jewelry shape: stud with screw kinda thing

Never downsized

Titanium

Used to use saline stopped after a while
