I can t always take a deep breath.. Symptoms went away for a wile.. Recently I painted in my garage and I have a similar ( Can t always take a satisfying breath issue ) .. I had smoked Meth in my younger years frequently .. Is it possible that exposure to the paint fumes triggered my shortness of breath? My doctor had diagnosed me with Anxiety issues and gave me Xanax in the past..
Thanks for your question on Chat Doctor. I can understand your situation and problem. Yes, it is quite possible to have allergy due to color fumes. They are known allergen. Whenever exposure happens, these fumes go in the lungs and activate allergic inflammation.  Which causes edema and bronchospasm. This causes wheezing and difficulty in breathing (not getting satisfying breath). And once exposure is over, inflammation is subsided, and you feel better. This is typical of allergic bronchitis due to color fumes. So better to consult pulmonologist and get done PFT (Pulmonary Function Test) to diagnosis and treatment for allergic bronchitis.
