My throat hurt when I swallow and it hurts my ear when I swallow and my grandpa was spraying red spraypaint in the basement what should I do?

See doctor. I don't know if the spray paint is related, but your throat and ear pain suggest an upper respiratory infection of some sort. Strep throat is a consideration, esp if you have fevers, and that would require treatment. Best idea is to have your doctor get the full history, do an exam and then treat you appropriately.
