I thought I was responding to one person (Barbara) but see you are another! I really don't know what the signs would be for the Amikacin?? I do cough quite a bit after the treatment and my voice is rather raspy now. I simply take swigs of the Kefir throughout the day and try to take my meds and nebulize in the morning after my walk. I now wear a mask doing yardwork, no hot showers, hot tubs, saunas or running thru the sprinkler. I live near the coast, and we have a community saltwater pool. I am having my tankless water heater cleaned next week and the temp raised to 135 degrees. I recently went to Niagara Falls and wore a mask much of the time. Cruise ships have in room refrigerators, and you can request handheld shower wand. Also check out https://connect.ntminfo.org/home another source for information.
