@Sean I took Biaxin (clarythromycin). I was supposed to take it for 10 days (1000mg) but I took it only 7 days. I had my left ear cloggued which the GP thought was caused by my sinuses. Biaxin cleared the ear but left me with a much louder T. While on it, I had vertigo, nausea, various intestine problems, loss of hearing, ear fullness, distortion, panic attacks, etc and of course a much louder T. (The T could be heard ABOVE the shower) All the symptoms went away except, of course, the louder T. T decreased slowly over the past few weeks (I took it at the beginning of May) but it's still not back to baseline.
I saw the ENT one week after discontinuing the antibiotics. I did an audiogram and my hearing was back to normal (I tested the frequencies 500 hz to 8000hz). I hear way above average. The ENT said he had seen such a reaction to Biaxin but he had NEVER seen an irreversible case in his career. He said the symptoms would go away, sometimes it takes a few weeks, sometimes a few months, it depends on the patient.
Was he bullshiting me? Perhaps. But it is true that the T has been going back to baseline. Sometimes, it's louder, sometimes it's like before, it depends on my menstrual cycle and my overall mood.
Hope this helps!
