Go find a different Dr. A co worker's husband kept getting "bronchitis" and his Dr. kept treating it as that. For as long and often as he had it, we told her he needed to see a different Dr. They waited a little longer till finally they listened and saw a different Dr. He had a fairly rare, but not unknown,illness, which if it had been caught earlier, could have been treated and possibly given him years before needing a lung transplant. As it turned out he received a lung transplant a few months later and lived for about a year after that. We all hope we have the Dr that knows everything but they are human.
