Examine your hearing aid batteries, do they look like they have corroded? If they do replace them with new ones.
Examine the battery's small metal prongs that connect with the hearing aid batteries when you close the device door. Do they look like they have corroded? Try closing and opening the device door to clean the metal prongs and then replace the batteries with new ones.

You might have switched the setting to a wireless one, which is generally used when using an assistive listening device. If so, use a different memory or program.
Check for blockages in the tubing or microphone openings, and clean them as recommended by your audiologist.
Check the battery voltage. If the batteries are low, it can affect sound quality. Replace them if necessary.

My hearing aids are giving me feedback

Remove your hearing aids and put them back in, as they might not be in correctly.
Turn down your device's volume. If the feedback continues your audiologist might have to re-fit your hearing aids, as the devices might have too much sound escaping through the vents or ear mold.
Your ears might have a build-up of ear wax, as this can cause feedback due to having to turn up the volume or sound bouncing off your wax.
If you have lost weight, you might have to have your hearing aids fitted again. For example, you might have to have new ear molds made to fit your new ear shape.
