2 years ago I started to become more sensitive to cats dander and would start asthmatic bronchitis which would not go away so I had to take ketotifen for 2 months. I decided to start immunotherapy with cat and dog dander. Everytime after shot I had a reaction. On the 7th month of the theraphy I developed shortness of breath, tightness in chest, I started to react to everything (cooking fumes, people s odor and etc.). So I started to take Montelucast along with Ketotifen 2mg twice a day and stopped vaccination. 5 months later symptoms got even worse (still taking medication). Now I feel like very second I have to take a deep breath, feeling like there is no room to breath in. I had blood test done ( Vitamin D came out very low and IgA very high), also I had a chest X-ray done (Hyperinflation of the lungs). Now waiting for PFT to be done and referral to a pulmonologist ( which I cant see sooner than in 2 months, they are all booked. I wonder, what is going on with me? Is it empyzema, COPD or just asthma? Allergist prescribed Pulmicort (should I start taking it?) Allergist is not aware of x-ray results. thank you.
