Hi @jkiemen Not sure if you were addressing question to me but I was also on IV amikacin and then inhaled amikacin due to cavitary lesions. Oh, and clofazimine because I didn't tolerate Rifampin but then later they tried Rifabutin and I was okay on that My PFT results are always good, maybe because I was a runner for many years. I do get short of breath when working out but I think that has more to do with being out of shape than anything.

I had the opposite effect. Rifabutin caused total body aches and I can take Rifampin. I did allot of exercising as well. Maybe too much. Maybe it compromised my immune system. I guess none of us ever know the exact time and way we contracted the condition,

@jkiemen Never know which meds are going to agree with us. I doubt your exercise hurt you at all. Time for me to get back in shape since I'm off meds. I put on 20 pounds once I got off meds and I did not need them. Weight was perfect when on meds. Food tasted weird and my appetite was low.
