I have this left over issue in my lungs after having the flu for 4 days, it’s day 5 and I feel fine except I have I guess you could call it a frog in my throat. It was a sore throat but now it just hurts when I cough but the main problem is when I inhale I feel like I can’t expand my lungs completely and I’m wheezing when I breath out, I think I might have acute bronchitis but I’m not sure if I need to go to the doctor.
