Hello,
Since you have a history of
Asthma you should not have sat so close to the launching site of the fireworks.
Now you are experiencing severe
chest tightness along with nasal irritation, it is indicative of your Asthma getting triggered.
Inflammation of the airways may cause chest tightness accompanied by
shortness of breath, coughing or nasal irritations.
You are suggested to visit ER, get physically examined. You may need
oxygen or inhalers.
In the meantime take warm fluids to get relief from the mucus build up in your chest. Try to stay in open space outdoors so that you can breath fresh air. Avoid doing anything that will irritate your lungs.
Do not panic, stay relaxed. Get examined at the earliest else it may result in the worsening of the symptoms.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Nupur K, General & Family Physician
