I am experiencing tightness in my lungs and throat, trouble breathing, sometimes heart fluttering, along with a sometimes severe raspy cough, no matter how hard I cough I can t seem to get my lungs cleared, I am a smoker, I would blame it on that, except this condition came on suddenly, one day I was fine, the next day the coughing started and has progressed since then, I did have a mild cold prior to this condition, but this is beyond your common after effects of a cold, the only thing I ve done differently is clean up an area infected with of black mold, it wasn t a lot of mold. . I m also on phintermine , I ve been taking it now for about 6 months. The only other medication I am taking is Synthroid.
