Should I take my baby in again?

Last time I took him in for puking out his milk and having trouble sleeping and they sent us home saying he was okay and was teething, I mean yeah he is he has 7 teeth now, but today he hasnt slept through the night and usually he is a great sleeper through the night, he looked uncomfortable and was clingy to me and wouldnt let me lay him on the bed, and was puking out every time he ate, and refused to eat his baby food and is very warm, his temp was 100.2 ferinhit, which ppl say is normal, he is also congested with phlegm and has a very runny nose, and has not pooped yet today but is gassy, the longest he slept was 3 hours, but he seemed a lil better after that nap but it still hot to the touch and refusing food and looks uncomfortable again, he is not tugging at his ear or hair, should I take him in the emergency this time instead of the clinic where the new doctors seem as if they are rushing everyone out of there? He is alert and breastfeeding, but is just not feeling well..
