Breathing difficulty

I am having breathing difficulty time to time along with sweating and runny nose. I am also feeling lack of oxygen in my head. My head feels light.

This problem starts when I eat something cold, sleep under cold Air Cooler, I sweat a lot and do not change my cloth, and so on. The problem exacerbates during night and rainy/cold weather. My breadth is short, and I can't sing. Sometimes I run out of air while I am talking.

The problem aggregated during the night, and seriously hampers my sleep.

I took some medication in 2012 which I don't remember. My problem was totally gone at that time. Now, it is returned again.

During previous few months, I took Kali-curb 200c, Sulphus, and Bryonia.

When I took Kali-curb 200c, it was gone for a month and then came back again. Sulphur which didn't work. I didn't continue Bryonia. Because, I needed a quick relief.

Nowadays, I am taking mainstream medication like Sulbutabol and Fexofenadine. I am taking them thrice a day they give me quick but temporary relief.

Any help?

I am in serious pain.
