I have had chronic bronchitis along with a head full of crud off and on since Feb. I have taken 3 rounds of antibiotics along with prednisone, a shot of rocephin, using symbicort daily, albuterol as needed (only a handful of times)on my fourth box of mucinex 1200 mg of guifennisen. In May at my 3 visit to my primary care giver, she said she heard crackles in my left upper lobe. Pneumonia did NOT show up on the x ray but they treated me for it anyway. I went to the Dr again last week and he recommended a referral to an allergist. Today my son serviced our whole house AC unit and found half an inch of black mold in the air handler- 4 yr old unit and we live on the water. Could that be the culprit? Last week the nurse asked me if I thought there could be mold at my work.....it had not occurred to me at all and now here it is in my house!!! Your thoughts??
