Very faint clicking noise when BP breathes?

[danipanda]

I noticed yesterday when handling Noodles that she was making a very faint clicking noise when she's breathing. The only reason I even heard it was because she stretched up onto my glasses and rested on my ear afterwards. I took her and listened closer and it was very faint but definitely a clicking sound. I know this can be a sign of an RI, so I checked her mouth and didn't see any mucus, no bubbles, and there is no discoloration in or around her mouth/nose. She isn't rubbing her face in her enclosure and there aren't any mucus smudges on the glass. So what i'm wondering is if a slight, very faint clicking is normal, or is it's the beginning of an RI? I'll absolutely bring her to the vet if I have to, but wanted some advice first. Any help is appreciated!

She's in a 20G enclosure
Her substrate is a cypress/aspen blend
Clean water every day
I spot clean when needed and clean/disinfect everything once a month
She has three hides, one on the cold side, one in the middle, and one on the hot side
Her temps are 76-78, 80-82, and 89-91
Her humidity stays anywhere between 55% and 65%
I've had her for three months and she was never missed a meal, she's on rat pups
She sleeps all day and comes out for a while at night, usually basking on the branch I have in her enclosure, does a tour of her home, and goes back to sleep.

Could she be going into shed or have a bit of shed stuck in her nostrils?

No stuck shed that I can see and she shed exactly one month ago today actually, so her going into another shed is possible. Although, she doesn't have a pink belly yet...And the last time she shed her belly was PINK! Just wondering why her going into a shed affect her breathing? Haven't heard that before.

Yes it can.

The fluid between the layers and the extra layer itself can narrow the nostril enough to make pops and wheezes.

Thanks! I had no idea... I'll keep an eye on her for the next few days and hope she starts to get pink or goes into blue. (last time she was pink for like, half a day and then BAM, she was in blue lol) If it's not her going into a shed, is there anything else it could be besides an RI?
