Take Ars alb 200, 4 pills 3 days and then report thereafter for further treatment. You need to see the food what you are taking.
Do exercise daily, avoid spicy, heavy and junk food, avoid alcohol and smoking
(if you do)
eat salads and sprouts, papaya to reduce gastric problem.
Don't be empty stomach, because it will cause acidity
and leads to burning and gnawing sensation.
We have good homeopathic medicines, for acidity, but for that we need to take whole case taking, so that appropriate treatment gets started.
