A week ago, i thought i had bronchitis because breathing issues and got antibiotics. my x-ray was normal. i'm still having issues on and off, it gets worse when i'm working a grill at work. i'm not wheezing or coughing, but my chest/lungs are tight?

The tightness in your chest suggests bronchospasm in reaction to an environmental trigger. A form of asthma should be considered and testing is available. Keep a diary of time, duration, type of symptoms and review with your physician. A Healthtap consultation is available. Avoid smoke exposure and keep work area clean. Discuss whether a bronchodilator may be indicated.

Allergic to grill smoke/fumes/ Prob due to virus and depending on which one you got it will take 2 weeks to get better but take 14 days. Dr. humor.
