About two days ago, I fed my new baby Sithis some worm. He had a little bit of worm dirt on his face (from inside the worm, not from the worm container) but I didn't think much about it. Yesterday, I noticed he hadn't wiped it off like he usually does, so I helped him get it off and saw that the sides of his cheeks had puffed out a little bit. I was hoping it was just a little irritation because of the dirt so I didn't do anything. Today I noticed that the swelling was still there, right under the eyes, and may be a bit worse. I also noticed he was 'clicking' a little as he breathed. I put betadine on the mouth like I was recommended when Harley had a mouth infection about a year ago.
He is active and tongue-flicking despite acting like he has a little congestion.

Just wondering, is there anything else I should do? His temps are already pretty high; around 80 ambient temp in the reptile room. I'm thinking I will keep feeding, but probably wash off any worm chunks for a little while so there's no grit to get in his mouth. Is there a maximum number of times a day I can use betadine? I would usually go with about three...
Also, if this doesn't clear up, at what point would you guys recommend getting a vet? I didn't have this option when Harley had a mouth infection but I'm living in an area where I could find a good exotics vet now. Mostly I'm just curious.

Hoping I caught this early enough that it won't really be a problem! The clicking noise has me a little worried though...
