i have had chest discomfort for over a month now. It has affecting my breathing significantly. i do have asthma but it has never really affected me before. this is a constant tightness in the chest in conjunction with difficulty breathing at times. during this period i have not had a legitimate asthma attack where i am gasping for breath. before the month that i had this i sinusitis. also about a week ago i was on a course of levaquin and 40mg of predison for 5 days then a weaning dose of 20mg for 5 more days the antibiotic was for all 10 tens. to an extent it has helped and today i feel a bit better but im just curious as to what could be going on as my dr is rather vague. also there is a small chance i was exposed to black mold. thank you.
