From post few months, i had some sort of sromach issues such as burping, heaviness in lower abdomen either on right side or sometime on left side. But today suddenly i had feeling of some sort liquid jumped up from stomach to throat which taste werd bitter and now my throat is little sore. I have a feeling of stomething stuck at the left throat and heaviness in left lower abdomen. After that bitter taste i had some sort of pinching rffects on my left chest which come for a seconds and go then again come and go. I feel like pinching effects changes the position in chest. This pinching effects made me some sort of anxious and i felt sudden panic situation. But when i burped out, i felt some sort of relief. Kindly guide me why it is happening? Is this issue due to heart condition or stomach?. In 2021 feb i had some sort of chest pain which is not sharp,a light pain so i visited a cardiologist he took ecg and tmt all went normal. Kindly guide me i am little anxious.
