Wisdom teeth are in pain and I had pain in my neck and jaw yesterday. Could this be infection? If if so what should I do?

See a dentist. A dentist specializes in the teeth and oral cavity issues. If you have some problem with your wisdom teeth or an infection, they would be able to diagnose you and treat you best. Good luck.
Infected. Usually when pain develops in wisdom teeth there is inflammation or infection. See an oral surgeon to helps sort things out.
