Hello everyone. Im a 21 year old latino male. I recently quit smoking about 2 weeks ago. I smoked for about 2 years, and i had 4 to 5 cigarettes a day. Well just last week i took a trip to the hospital, because i started getting chest tightness and shortness of breath, While i was in the car. So i went to the hospital, they checked my pressure, they did an EKG, and they took an X ray of my chest! The doctor came in my room, and told me i was healthy and both my lungs and heart were good. He told me i had a anxiety problem and i had a panic attack. But when i went home i still have the tightness of my chest and waking up at night with pains. Im living in fear that i could have an attack, and not wake up. I feel like i will never get better i dont even want to hang out with friends. Please give some insight, if i have something bad with my health. Thank you!
