The symptoms as mentioned in your post can be due to:
1. Strained chest or upper abdominal muscles 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
Though symptomatic relief can be obtained by intake of anti spasmodic & antacids, the underlying cause needs to be treated to prevent recurrence.
So, it will be better to consult a Doctor & get a physical examination done.
Investigation like Ultrasound
scan of abdomen will be helpful.
Wishing you a Good Health.
Thanks & take care.
