Please take heart...13 years out without treatment thus far. Variety of NTM strains over the years. Walking 2-3 miles per day, no O2, reasonable (and grateful for) quality of life. Doctor at NJH has honored my "watch and wait" approach although would prefer that I were on meds (tried twice, not tolerated). As evidenced by all of the wonderful contributors on this website, there IS life after diagnosis. Lean in...they have great info.
