Hi, I am Dr Sonia S V. I am an ENT Surgeon[Specialist in diseases of the Ear ,Nose ,Throat and Head and Neck Surgery] .You may be suffering from what we call a post nasal drip[ here secretions accumulate in the throat from the nose. As you gave a history of viral infection earlier post nasal drip seems likely. Acid reflux
issues can also lead to increased secretion. You can try steam inhalation but if the issue persists Visit an ENT specialist
in your locality .
All the best
Dr Sonia Suprabha Venugopal
