or tightness can be caused by various reasons, including minor problem such as indigestion
or stress, to serious medical emergencies such as a heart attack
Other causes of chest pain/tightness include:
1. Strained chest muscles due to overuse
2. Chest muscle injury
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 a Good Health. Let me know if I need to clarify further.
Thanks & take care.
