Hi and welcome to HCM,
I have gone through your question. To reduce acidity you can add vegetables like cabbage, carrot, cauliflower, green beans, mushroom, peas, pumpkin. Also fruits like apricot, Apple, Banana, Blackberries, grape, strawberries, tropical fruits can be taken. Avoid junk foods, acidifying grains and animal protein which causes acidity. Nothing to worry. Intercostle nerve
operation can be done as per doctor's recommendation.
Wish you speedy recovery
