Hi, Monday I Was Cleaning Out A Closets That Had

Hi, Monday I was cleaning out a closets that had clothes that had been there for over 15 years. After a while I felt my chest tighten so I opened the door. All went well until about 2 a.m. the next morning. I woke up with nausea, absolutely no strength to move and a slight fever. My husband got me ginger ale. I felt a little better but slept all day Tuesday. Today I still have an awful cough with rattling, chest paid, and a bit of mucus. Could I have inhaled some kind of toxin? What can I do about the cough and chest pain?
