I Had Chickenguniya Three Months Back And With That, Chhale

I had Chickenguniya three months back and with that, Chhale (sores) which continued for
20-25 days. Now, these are normal, but sometime there is pain while drinking normal water
or sometime hard food. ENT doctor said there is nothing and also I saw another doctor, he
said likewise. Kindly advise what is the reason.

Thanks Ramesh Sharma
