I am a 20 yr old male, Smoking since 3 years. I have a lingering dull pain in the left side of my chest since a month now. Its not a bad pain but its surely noticeable and discomforting. Never before this pain has been triggerd by smoking. But yesterday it started after i had a cig. It usually subsides after a while. Breathing dosent affect the pain. And i have no problems breathing. I've taken chest x rays,bloodtests and ecgs/bp which all came out normal.
The doctors say that its all because i think about it a lot. Also I had a anxiety disorder..but im over that. The doctor said its acidity because my diet hasent been good for the past year. But not anymore.
Is this heart related?
I really want to know what causes this pain and how it can go away.
