Healing signs:
No redness or discoloration is present at piercing site
No “crusties” or other discharge is present and hasn’t been noticed in ~6 weeks
The piercing openings are smooth and flat
The piercing itself is not thickened, no healing-ridge is present
Piercing area is not painful*
*Many piercings have little to no pain at all during healing which makes it difficult to use pain as a metric. But if there is any pain at all, stop all attempts to remove jewelry and begin hot water compressing immediately. Let the site rest for a few weeks before attempting another changeout and prepare well in advance.
