Hoping for some help. Started with sore throat, swollen glands and sneezing for a couple of days. Now I feel like there’s an anvil sitting on my chest and lungs have burning sensation. It’s definitely getting worse not better. I can feel it going deeper in to lower respiratory tract and getting gurgling noises in lungs. I can’t get out of bed. What point do I seek medical advice. I know it used to be if you can’t breathe and blue lips
