Chest pain/tightness can be caused by various reasons, including minor problem such as indigestion
or stress, to serious medical emergencies such as a heart attack
The symptoms as mentioned in your post suggest that it might be due to Obstructive lung disease
. So, investigations like X ray and Pulmonary function test can clinch the diagnosis.
Other causes of chest pain include:
2. Strained chest muscles due to overuse
3. Short-term, sudden anxiety
with rapid breathing
4. Peptic ulcer
5. Pain from the digestive tract, such as esophageal reflux
So, it will be better to consult a Doctor & get a physical examination done to rule out other causes. So that proper management steps could be taken.
Wishing you a Good Health. Let me know if I need to clarify further.
Thanks & take care.
