I'm wondering the same thing. I've had mine for almost 2 months now and it is still red around the outside of the post! :(
No more than 2-3 weeks. But, if you hit it or snag it of course it might get red but the constant discoloration shouldn't last long.
If its been red,itchy and swollen for more than 2 weeks, if theres yellow/green drainage from the piercing.
When you first get a piercing, redness aroud it is perfectly normal. Depending on where it's pierced will determine how long it's going to stay irritated. Most of the time a piercing will be red for the first 2-4 days and be swollen. If it persists then I'd go back to the piercer.
depends where you piercing is
How long a red tailed catfish can stay out of the water depends on the fish in question and how moist the fish's gills are.
as long as they want to
it will stay a red giant for a couple of million years
-yellow/green discharge from piercing -pain or tenderness around the piercing -red, purple, or yellowish discoloration around piercing
2days.
It will have the Red Ring of Death for about 3 years +
Actually not long at all. See it's the clothing and shirts and other layers that cause irritation to the navel piercing. If the piercing were done and left uncovered except for sleeping (bed sheets etc.) the piercing would look not bad maybe a very small red circle around the top exit point. So redness comes with the territory of clothing and irritation, this can be expected for a period of 3 to 6 months depending on the weather and the amount of clothing you wear over the navel. Remember regardless of what anyone tells you who isn't a professional body piercer navel piercing take a good year to heal and become seasoned* (* toughened up). So be nice to it and when possible give it all the fresh air you can.
when the area around the piercing is really red and looks like it has blisters on it.
