Welcome to Chat Doctor . I have gone through your query and can understand your concern. As per your complaint there is a possibility that your brother is suffering from viral infection leading to fever and blisters on tongue. I would suggest you to consult an Infectious Medicine specialist and get evaluated, and he can advise you anti-viral Chat Doctor. . Continue taking Paracetamol for reducing fever. He can be advised to gargle with a numbing mouthwash containing Lidocaine for relief from pain in sores in mouth. Take multivitamins daily. Take a soft diet. Take ample of fluids and appropriate rest. Hope this information helps. Thanks and regards. </s>
