I have been on Baxin/Plaq combo for the better part of the last two years. I recently saw an ENT for swallowing problems. While there he also gave me a hearing test which noted I definitely had hearing loss in my right ear. I also have balance/vertigo that luckily is not as bad as it was two years ago when I first got my Lyme Clinical diagnosis.
The deafness and occassional ringing in ears may be from 35 years of doing lighting and sound for Rock bands, as well as sometimes playing in the bands. Or it could be Biaxin/Plaq related. Or a combination of both.
The one time I went off antibiotics, including the Biaxin/Plaq combo I got very sick.
