Hi @willows I do not have asthma but my daughter developed it during her childhood. She is now in her late 20’s and gets the tightness although she loves cats and dogs. She went to an allergist and discovered that she was allergic to pet dander on top of her asthma. Every time she visited me she had to take an allergy pill because of our pets. It didn’t stop her from owning a cat. She now has a dog. After seeing the allergist for 2 years, her allergy level significantly decreased. Perhaps seeing an allergist will help with your symptoms. Initially she did have to go through a series of tests for the doctor to custom make a medication she received. As time went on she needed it less often to suppress her immune response. She had no problems when receiving the covid vaccination. Hope this helps. Toni
