I started coughing with a sore throat on monday and have had very little of a voice. i smell a bleach like scent in my nose and when it happens, my head gets really tight. whats going on?

It is likely that you were suffering from a viral upper respiratory infection. It is possible that it could even be from influenza or Covid. I would see an urgent care doctor or your primary care doctor to get tested. In the meantime, stay hydrated and try to avoid contact with others to avoid spreading the illness. If your breathing worsens, go to the emergency room right away. Good luck.
