I had exactly this! I kept having flare ups and couldn't figure out the pattern until we tore up a bathroom and discovered mold. Suddenly I realized my lungs hurt everytime I had people come stay over. They'd use the spare shower, it'd excite the mold and then I'd need an inhaler. Cheap hotels also put my lungs into a tizzy. Definitely worth checking cause mold is everywhere.
