Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that the symptoms of blisters on tongue along with mild fever and
sore throat are indicting towards viral
throat infection..
Infection can lead to inflammation and blister formation over the tongue..
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like throat swab culture can help in diagnosis and treatment can be done accordingly..
-You can be advised to take
Acetaminophen to relieve fever and aches..
-Do warm saline gargles..
-Gargle with a numbing mouthwash containing Lignocaine..
-Take vitamin B complex daily..
-chew a
Vitamin C pellet and suck throat lozenges..
-Avoid spicy food and take a
soft diet..
Hope this information helps..
Thanks and regards.
