Brief Answer: Viral infection, probably herpangina Detailed Answer: Dear XXXXXXX Thanks a lot for your query. By the description of the symptoms, this is most likely a viral infection, and the most compatible one would be a syndrome called herpangina, caused by a Coxsackie virus, and causing quite painful lesions inside the mouth, in the lips and rarely in the hands and feet, along with fever, sore throat, headache, congestion and malaise. The treatment is supportive, with analgesics like iburpofen and acetaminophen for pain and inflammation, magic mouthwash to alleviate the painful oral lesions and benzocaine lozenges also to numb the oral cavity and allow eating and drinking. Hope this helps, Happy Holidays, Dr Brenes-Salazar MD Mayo Clinic MN
