Thanks for advice i will follow up with my doctor .
Hello and hope you are doing well.
Repeated throat infections could be due to sinusitis. It could also be recurrent tonsillitis. It could also be due to allergens. These are substances like pollen, dust, animal dander, certain foods, insect venoms and certain medications. Exposure to allergens causes a runny nose with a resultant post nasal drip where secretions from the nose go backward into the throat and irritate causing throat congestion. You will need to consult your primary care physician for proper clinical assessment. In the meantime for relief from your symptoms you could do warm salt gargles and take OTC antihistamines.
Hope this helped and do keep us posted.
Ask your doctor to refer you to an ENT. The ENT may give you different advice!
