Hello dear parent ,

I understand that your son is suffering from infection. Dear parent ask your son to pay a visit to a doctor near to his campus . There must be some good physicians there or your son can talk to his some teacher in the campus if he can take few days leave or medical leave so that he can come home . Then you can take him to doctor for check up . If the condition diagnosed be not so serious then your son can go back to college in 2 days for other wise he can take prescribed medical days rest at home . I hope this was helpful to you

Best wishes
