Do you have pain/tenderness in the front of your neck? Do you have fever? The 8mm
thyroid lesion is not responsible for the hearing loss, but please meet an ENT specialist to rule out an ear infection/eustachian tube blockage. If there is neck pain it may be due to subacute or acute thyroiditis. Subacute thyroiditis is self resolving but some times takes many weeks to resolve. You may require steroids/NSAIDS
