Help Needed! Swollen face, eyes, spots, and fever!!

[2BullyMama]

Day 3.. he has now begun to throw up his food.. he threw up his breakfast and dinner.. he still has some hives bumbs on his legs and belly and i noticed a tough scabby looking thing by his rib which i presume to be a hot spot.. his face and breathing are normal, it might be that the daily doses of benedryl might be making him bring his food up.. gah.. I just want him to be back to normal :l

Could just be upset tummy from environmental allergies. My boy used to throw up all the time when his allergies were real bad
