hello and welcome to HCM,
The development of tinnitus
or the sound in the ear is usually not a good sign especially since you already have hearing loss
and are using hearing aids
It may indicate a further worsening of hearing or weakening of the nerves or sometimes may even happen in case of an infection causing block in the Eustachian tubes of your ears.
In any case the ENT may do a full examination of the ears and order an audiometry
so that a better picture of the nature of the tinnitus may be ascertained. He may also ask for an imaging study if needed.
You may ask him to also rule out any neurological/ ortho problems
Finally you may ask him about this new prostagladin analogue called the TINNICAR which i have found a fair amount of success in treating essential tinnitus.
take care and hope you recover
