Yes, wax buildup can cause hearing loss. I had to have my ears flushed before. My cousin the public health nurse would flush them every few years. A little hydrogen peroxided in warm water, then gentley flushed with a rubber syringe. Think little soft turkey baster type. You can buy kits at the drug store or the nurse in my current doctor’s office offered to do it. She brought out this horrible looking huge pump. I declined.
