Hi,
Welcome to health care magic,
It could be due to upper
respiratory tract infection like pharyngitis.
Majority of cases this infections are due to viral infection(EB virus,adenovirus) but in some cases it might be related to bacterial infection (
streptococcal pharyngitis ) but needs to checked by clinical examination.
We differentiate the cause through routine blood counts with throat examination, pharyngoscopy to rule out non infective causes.
Therefore it is advisable to see ENT specialist for thoroughly clinical examination.
Your son might require antibiotics (to prevent super infection if cause is viral) with analgesics, antiinflammatories and steam inhalation 2 to 3 times a day with expectorants syrup.
Here,he should also take
cheratussin Ac syrup as it contains Guaiphenesin which is an expectorant and helps to loosen congestion from chest and throat, making it easier to
cough out through mouth.
Warm salt water gargles which helps to get relief from throat soreness and irritation.
I hope it will clear to you now that what exact treatment is to be taken in your son's case.
Consult ENT specialist for further advise.
Thanks and Regards,
