Hi Bon,
I had issues including tinnitis and ear pressure/pain with taking Azithromycin as well. I was placed on Clarithromycin and the ear pressure/pain stopped however the tinnitis continues. As for sores on the tongue, I developed these when taking Moxifloxacin several years ago, they went away when I stopped taking the med. Good luck and hope your doc can find meds that will work with you!
