I've had Tight chesst and shortness in my breath for nearly 3 months, in the beginig it used to come some days, but now it's every day, i feel i dont get enough air into my longs, I'm 23 and i smoke 6-8 cigarettes per day,
I had a SperoMetry and chest X-ray. nothing seemed to show up.
My doctor advised me to take tranquilizers. but I only used them for a few nights. right now,left part of my body has pain, I think it's because of me trying to take deep breaths.
I hope you can help me.

Thanks...
