I'm a bit worried because I did an RTPCR test for COVID and it came back negative, but I'm still having trouble with wheezing in my chest and some coughing for about 45 days now. I don't have a fever or other symptoms, and the breathing difficulty isn't too bad, but the wheezing is definitely there. I have asthma and normally use my Serflo 250 inhaler only around 10-15 times a year. Just recently, about 5 days ago, I had a really bad allergy attack. I'm not sure what to make of all this. What should I do?

Patient is advised to continue seroflo 250 inhaler sos for breathing difficulty.
