Many causes: There are multiple causes that may explain your symptoms. If you have a history of allergies or asthma, please follow your asthma/allergy plan. Avoid smoke, dust, mold, pollen and animal dander. If you have not been diagnosed, please have an evaluation for infection, muscular strain and an allergic reaction. Cardiac causes are less likely but may be considered by your PCP.
