His only symptom was his sinuses always being what his Ped. referred to as "sounding swollen." He doesn't have a runny nose he sounds like he is impacted and alwyas has a dark bruise looking strip across the bridge of his nose. He also has a history of vocal cord dysfunction (cords don't spread apart when he draws in a breath) This causes him to sound like he is wheezing on inspiration. Asthma meds have no effect.
May be he had mononucleosis. Mono is usually linked to the Epstein-Barr virus (EBV), but can also be caused by other organisms such as cytomegalovirus (CMV). I don't think Anti-Thyroglobulin antibodies are related. Did he had any kind of symptoms? did he test for liver enzymes? Yes allergy can cause high eosinophils.
