Strep throat is generally a mild infection, but it can be fairly painful. Sore throats, fevers, and swallowing pains are the most common symptoms of strep throat. Additionally, there can be swollen lymph nodes at the front of the neck, large, red spots on the roof of the mouth called petechiae, as well as red and swollen tonsils. Children may also experience headaches, stomach pain, nausea, or vomiting. There may also be a rash associated with strep throat, known as scarlet fever.
