Thanks for the follow-up.
I understand your concern.
As per your description,possibly it's Gastroesophageal acid reflux.
And you should try OTC Zantac and Gaviscon.
Also maintain a good hydration.
Take OTC Aspirin.
Avoid hot,spicy,fried diet.
Other possible differential diagnosis may include Costochondritis.
Take OTC Advil.
Do gentle massage with topical diclofenac sodium ointment.
Avoid alcohol and smoking consumption if you take them.
You should elevate your head with an extra pillow while sleeping.
If your symptoms'll not show any improvement with such self care remedies in next few hours then visit ER.
EKG,chest X-ray can be advised.
However chances of heart attack are very slim.
Feel free for further queries. It's good to discuss rather than quit.
