Thanks, all. There's been so much, I guess I left some out. Bubba gets 5 benadryl 3 times a day. Right now I think it is just thickening it up. Our allergies are all bad right now, and that could be a part of the problem, but they are green, so that's infection.
He did have a CT during the x-ray/biopsy/lavage trip to the doctor. Those all showed nothing. Just lots and lots of snot.
