Hi,thank you for posting your query on health care magic.
You are suffering from repeated infection in the ear and throat.
Nasal infection might be a cause.At present,you are suffering from sore ear.
It would be advisable to have Nasal secretion or
ear discharge if present to be sent for bacterial culture and antibiotic sensitivity to know that is it a bacterial infection,if yes-then which bacteria is causing infection and to which antibiotic-they are sensitive.
Also do a
blood test for
Complete blood count to know the level of infection,and Random Blood sugar-to screen for
Diabetes.
Avoid eating cold,spicy,oily and junk foods.Drink warm turmeric milk.Eat food like Amla,Lemon,etc which increase your immunity.
It would be advisable to consult an Otolaryngologist Doctor.
Hope this answers your question.Get well soon.
