Is it possible for my 6 month old to be vomitting if he is teething?

there has been no fever, he has had diharrea, and doesn't feel like eating his cereal or fruits and vegetable he just vomits them right back up. He has been checked by doctors twice for weeziness and has been put on 2 inhalers and amoxicillin but after about a month of that those symptoms have returned. is this apart of teething as well?
