Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your wee one’s situation, and wanted to help.
Again I do apologize that my colleagues could not aid you sooner, but can you tell me:
How much does he weigh?
Is he on the aspirin now? Are you giving it every 8 hours?
Does the eyeball look swollen?
Has the facial swelling gone down or gotten worse over the past few days?
Any chance of snake, spider, or insect bites?
Can you take a photo of this? If you can do so and post them online, it will let me see what you are seeing. To post them, you can either use the paperclip on the tool bar. Or if you cannot see that on your phone/computer, then you can post them on any site (ie Flickr, Photobucket, Imgr etc) and paste the web address here for me to have a peek.
