I've been dealing with a pretty bad indigestion issue. So, on June 1st, 2020, I just up and quit smoking. I was smoking about 45 cigarettes a day for the past 10 years, but I started cutting down in 2018 and finally stopped after two years. The first few months, I had headaches and an upset stomach, but recently I've had a bit of trouble breathing. When I do things like running or cardio workouts, I feel okay, but if I miss a day, I notice some shortness of breath and my throat feels tight. This has been going on for a month, and I've been feeling kinda weak, too. Is this normal, or could it be something else? I don't have any other symptoms.

Salbutamol inhaler and budesonide 200 sos is advised for breathing difficulty.
