windwalker and all on tobramycin I'm writing to ask if anyone else is having trouble breathing after using tobramycin. I went to Mayo's and they tested me with one application of it and all seemed fine. After I came home and used it about 10 days, I really have trouble breathing. Hard to lie down at night and during the day I oftentimes have to just sit down. Am wondering if anyone else has this experience and if so, are there any suggestions. I know I need to take it but it is very difficult (and sometimes scary). If there are any suggestions, I would love to have them.
