Still Testing Negative, but...

So, I'm still testing negative for COVID but I am feeling quite lousy... coughing up a lung every few minutes...  also with barking coughs...  chest congestion and coughing up phlegm...  and just generally feeling lousy...  and tired.  I've been doing so much coughing that I'm sure the neighbors must think I am dying of COVID in here.  

It is time to make lunch but I just want to lie down and sleep. 

Coughing sometimes hurts in my chest but hurts my head most of the time.  I don't have a headache but my head pounds with each cough.  This is a really strange illness that I've never experienced before in my life.  It is very, very hard to believe that I am truly testing negative for COVID.  Then again, I have very little faith nor confidence in the accuracy of the COVID tests.
