My 2 1/2 year old son had the flu and took tamiflu. A week after his symptoms got better he gotta a fever again for 3 days. He developed a large blister on his lower right lp and sores in his mouth. His teeth are sore and he cant drink eat or swallow much. His gums are red and swollen and bleed if we try to brush his teeth or he eat anything hard or crunchy. The doctor gave us amoxicillin but didnt diagnose anything and his mouth is still red and swollen, 6th day. The blister on his lip did not turn in to a coldsore. Its like an ulcer now that it has popped.
Doctor's Answer
Hi,
As per your description and keeping in account the age of your dear son, it looks mostly a primary herpetic gingivostomatitis to me.
Give more of supportive treatment like ice chips and some coating agent for ulcers like kaolin pectin.
Take care and visit any Oral Physician
