5 days ago I experienced slight headaches and stuffed nose. I took tylenol extra strength for 4 days, but I didn t heal yet. I had no high temp at all. Now it s my 5th day stuck in home due to my sickness, my nose is still semi-stuffy, and developed really severe coughing and trouble breathing and sleeping at night. My heartbeats are also mainly fast, and I think I feel my pain from breathing from my lungs, not my throat. Plz advise? Thx
