My mother (93yo) has hearing aids. However the hearing capability often goes much worse. Also, it occasionally goes much better (then she hears quite well without hearing aids. She is in relatively good health for her age. Visited many hearing specialists, always determined quite clean ear pathways. Sinuses are not diagnosed as problem. Ear specialists do not see any problem. Never feeling dizziness, but sometimes feel full ear. Sometimes wax obstruct aid tube. Before having aids she had strong tinnitus, which is almost eliminated with obtained hearing aids. She has long morning sneezes, takes regularly medicines for hypertension and for glaucoma. Still the very large problem is the inconsistent hearing.
