Probably best to have a vet check it. In the mean time put some unpasteurized honey on it.
Here is a website to find a vet if you are in a small town type in a bigger cities zip code

Honey is very good for healing --- in the mean time how old is the dragon? What size tank is he in and what kind of UVB are you using? We need to figure out if its hormones causing the glass surfing if the tank is too small or if the lighting is causing the issue
please NO coils for UVB NO colored bulbs NO off white or yellowish basking bulbs and if your using a MVB what brand certain brands cause eye issues and emit certain rays making it uncomfortable for dragons they also do not provide adequate UVB rays as well
basking temps what are they and how are you taking them? NO stick ons please you want a digital probe thermometer and you want surface temps they are the most accurate
