Hi
Thanks for posting your query on HCM
Persistent cough, cold and
sore throat may be caused by a respiratory infection.Most of these infections are of viral origin and may need only symptomatic management.However, bacteria infection or
superinfection are possible and will need antibiotics.With a past history of viral infection, it may just be a relapse or a bacteria superinfection or just
allergy.I will suggest you see the Doctor for examination and a throat swap smear test/culture given that symptoms are persisting.
In the meantime, you may try the following:
-Take an antihistamine like loratadine
-A
steroid like prednisolone
-A
mucolytic like carbocysteine 5%
-Gargle with warm salt water many time per day
-Avoid environmental irritants like dust, cold and smoke
Further management may be after throat examination and tests by your Doctor.
Hope this will help
Wish you a speedy recovery
