Last week I had very intensive work from home plan with almost 11 hours of working sitting on chair for prolonged hours. Then since 5 days ago, I had pain in my abdomen on the left side. Gradually I started feeling pain in my left chest and sometimes near to heart with constant burpings. Since last one week I m only having hot water, turmeric water, controlled simpl diet without any non veg and no spices. I started walking for 2 hours. But still the pain is persistent. Kindly suggest remedy. Thank you.
