Thanks for the query
Symptoms may be due to Herpetic infection. Swollen lymph nodes
are also due to oral lesions.What you need to do is maintain oral hygiene
moth wash, apply Zytee lotion over the lesions 4 hrly, give multivitamin
syrup 5 ml once a day, avoid acidic and irritating food. Give paracetamol
asyrp. and do tepid sponging for controlling fever.Watch for persistence of high grade fever, any rashes over the body and any other obvious signs. If it is herpetic infection or any other benign lesion it will subside by these conservative measures. If condition worsens consult your doctor immediately.
