I'm dealing with some chest pain that's been bothering me since January. I've done an ECG, echo, TMT, chest X-ray, and sputum test, and everything came back normal. The pain has decreased a bit since then, but it's still there. Plus, every morning at around 5 am, phlegm comes up, and I notice a bit of a cough when I exercise. Also, my chest starts getting irritated when I sit in an A.C. environment. Could you suggest some precautions or any advice on what might help? I'm really looking for some guidance here.

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