I'm a non-smoker and had a case of tuberculosis back in 2015. For the last 1.8 years, I've been dealing with a buildup of phlegm, and I just found out my IgE level is 489 IUml. Could this mean I'm dealing with asthma, COPD, chronic bronchitis, or something else? I'm really worried about whether this could cause more damage to my lungs over time. What do you think?
