shedding and mouth bubbles

I went to mist my chameleon tonight noticed he was shedding. I love to watch their skin just kind of explode off of them, so i have been going back several times to see it pop off lol i noticed he had climbed to the top of one of his plants where the heat lamp is and he had bubbles around his mouth. this is the first time this has happened that i have seen. should i worry about a URI?

URI is definitely a concern here, but don't get too worried until we're sure.

Is it possible to post a picture of these mouth bubbles? Does he make noises when he breathes?

hes only done it the one time. hes still shedding so im keeping a close eye on him. no popping or cracking when he breaths and no heavy breathing. he isnt elevating his upper body. he hasnt lost weight. his urates are a little yellow, so im going to mist a few more times tonight before i go to bed and hopefully ill see an improvement in them tomorrow
