migizii - I am not a doctor, but live my life surrounded by medical professionals, and I know there are MANY infections which are not treated unless you are immuno-compromised. The folks at Mayo are among the best in the field, my brother sees them, and trusts them implicitly. If you feel like you are getting good care, go with it! Also, the purpose of the respiratory therapy is to bring up the mucus, so sounds like it's working. Just be sure the doc explains when you should be in contact if your condition changes. For example, in September, my doc said he would see me in April, but just recently his nurse said he wants to see me in February instead.
