Do you have animals at home? If so you should try and get someone to look after them, outside of your home. My constant chest pain left me and only returned if exposed to a fur bearing animal or feathered bird. It took about 3 weeks after the animals were gone for me to feel a significant reduction in pain. It’s not their fur or dander that causes allergies it is their breath that contains invisible partials that float in the air and that we inhale as we breathe. Physicians tend to test for allergies which can be readily recognized as a biological process having to do with the immune system. Irritants on the other hand can be awfully painful but are not tested per se. In cases like ours it is really important to discover irritants as well as allergies. For example, irritants for me include, smoke, aerosols, fumes, certain brands of glass cleaners, etc. These can give me the chest pain in a more limited way. So I suggest that you try and identify your irritants and make the necessary changes. The medical profession can’t do this for you. Good luck, I hope you make progress. It’s awfully hard to place a pet elsewhere as they are members of the family, but sometimes it has to be done. Hope this helps.
