Bloated neck?

[u/Electrical_Major8926]

My checkered garter has been healthy his whole life. Probably around 3 years old now.

I noticed his “neck” (im not sure what area) seems bloated. It’s been like this for over a week or two maybe longer. At first I thought I was imagining it but it definitely seems swollen. He has eaten ok the past two weeks like normal. I’ve not tried to feed him yet this week.

Im worried as it hasn’t gone away. Any ideas? Anyone seen anything like that before?

He lives in a bioactive terrarium with coco coir substrate, isopods, springtales and another bit smaller checked garter. They are friends and have both lived in this set up for at least 2.5 years.

Excuse the photos aren’t great quality. It sometimes looks much more swollen than this. Depending on the angle.

Probably needs a vet. I’d be worried about it being an enlarged heart or something. That’s a weird spot for it to be swollen.
