How much skin should be between the piercing bars on a naval/belly button peircing?

[Anonymous]

I have had my naval piercing for almost 6 months now when I first got it there was so much skin in between the balls that I couldn't see the bar. That shrunk. And there is a lot of the bar. I thought of rejection I also have redness on the top hole. Which move from the left side to the right. This red is not light though it is not painfully or sore it's dark like a small bruise and only on the right side of the whole. Anyway I don't have pain, flaking, dryness, itchyness or puss.
I went back to my precessional piercer who told me a had a small infection and to clean it with soap then do the salt water spray
However I've been going this and the redness has not gone away, or lessened.
She didn't say it was rejecting just that there was a small infection. However when I look online the small infections are bright red and the ones that are called bad or really infected. Look like mine as in redish purple, the skin has not gotten any smaller it is not flany it is not painful and it if not bloody or has puss.
So what gives? How much skin NEEDS to be in between the holes or bars? And how bad is my infection?
She also said it could haveasily been the jewlery I have and she changed the metal I was peirced with to something else

Your piercer doesn't sound very professional.
Infections don't happen in well done piercings.
Inflammation, yes.
There should be lots of bar to be seen in a new piercing.
That's to allow for the swelling so that the ball doesn't dig in, get gross and reject.

He pierced you with way too small of a bar, and maybe did it too deep by the sound of it.

I'd go to a different, more reputable place and have them decide.

That's kind of the thing though a woman pierced me and I had a big bar the skin got smaller but not to the point where it shows rejection like flakiness or blood it's not painful either. When I went to get it checked I got a different peirced and they told me it was a small infection. That should go away in a month if I followed her steps
Either that or ito irritation possibly bruising because I still sleep on my stomach.
And when I went to the other one she changed the bar for something shorterthat looks better and doesn't hang as much but I'm still paranoid about the redness.
It doesn't show signs like an infection. No puss no pain no flakes no discoloration of discharge there isn't even disagree anymore.
