Hi Falconfly,
Experiencing hissing in your ears must be very distracting and concerning. To have your concerns ignored, frustrating! Your use of ALL CAPS really shows your understandable anger. There are several members talking about constant or repeated sounds, perhaps your symptom(s) is similar to the experiences shared in one of these discussions:
- sudden hearing loss followed by unbearable tinnitus https://connect.mayoclinic.org/discussion/sudden-earing-loss-followed-by-unbearable-tinnitus/
- Hearing repeated sounds and echo in my ear. https://connect.mayoclinic.org/discussion/hearing-repeated-sounds-and-echo-in-my-ear/
- rapid thumping sound in left ear https://connect.mayoclinic.org/discussion/rapid-thumping-sound-in-left-ear/

Is the hissing constant? Do any of the experiences shared in the above conversations mirror yours?
