I've had quite a bad productive cough since last week, it's worse at night and I am wheezing a lot. I find I have a constant pressure in my chest and am much more aware of my breathing, I have also noticed a very rapid heart beat. I have other flu like congestion symptoms such as a runny nose and blocked ear. Up until today it has been extremely painful to look up with my eye or to the extreme sides. I have also lost about 3 kilos unintentionally in the past week.
