Hello,
Has he recently shed on the head/eye area? It could be some shed that got stuck & has
irritated it to the point of infection possibly. How long has it been like this?
Does it seem to be bothering him at all right now?
Does he bulge his eye/eyes during the day or just at night when he sleeps?
If it doesn't seem to be infected, it would probably be a good idea to get it checked out in case
there is an abscess developing for some reason. A clogged sinus gland possibly that can be
causing infection, or pressure that isn't draining properly, or a clogged eye duct/tear duct.
How is his appetite?
