Hi, My 9 year old daughter started with a sore throat (at the front base of her throat) in May 2019. She has had cameras down and an allergy blood test, nothing unusual came back (just waiting for a referral to private MRI due to the backlog for children's hospital). It disappeared toward the winter time and came back in April this year, again doctors are unable to see anything. Wondering if anyone has heard of any allergies that could cause this or experienced anything similar x
