Chest heaviness under left rib. Issue.

Hello I have chest heaviness feeling under left rib whenever I ride bike it feels more and feel more sensation like touch clothes on chest feels heaviness. This heaviness just under the left rib without any pain. My bp is 116/78 and pulse is 84. 14 days before I go for ECG cardiologist says it is normal but sinus tachachardia which is normal. I shows report to 3 different cardiologist on practo. They all suggest it's is normal and not need for ECHO and TMT. But last 2 days I feel more sensation in chest my clothes also feel in chest. Nothing any thing else. Please suggest it is serious or normal. I tell you one more thing I am living alone mom and dad no more. I eat on dhaba. Sometimes acidity and gastric issue are happens with me. Please suggest me. I am so much worried. I used spit tabacco for last 10 days because of breakup issue.
