Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that the
white spots over the tongue following an Upper
respiratory tract infection can be either apthous ulcers but can also be due to viral infection only leading cold sores caused by
Herpes simplex virus infection..
So to confirm what is the exact cause, you need to consult an Oral Physician an get evaluated and a thorough clinical evaluation and investigations like Oral Swab culture and
blood test can help in diagnosis and treatment can be done accordingly..
As of now in case if the spots are sore you can apply numbing gel containing Lignocaine over it..
Do warm saline gargles and avoid spicy foods to prevent irritation..
In case if after investigation viral infection is ruled out you will be advised oral and topical antiviral medications like
Acyclovir, Valacyclovir, Famicyclovir etc..
Hope this helps..
Regards.
