Laft arm numbness and chest pressure.

Hello doctor, i have been suffering from cardiophobia for 3 months. My blood pressure ranges from 130/80 to 150/90. I am taking sartel beta 25 for bp. I have gone through several investigations which are as follows 1. Ecg: 15 times in which 7times it was normal. 5 times normal with sinus tachycardia.2 times slight st sagging, 1 time slight t wave flattening. 2. Echocardiogram normal with LVEF 61% 3 CT coronary angio normal with left dominance and zero calcium score. 4. CBC: normal with Hb 13.8 5 CRP: 2.05 mg/l 6. Lipid profile: normal range 7. Thyroid: normal range 8. HbA1c : 5.5 9. Fasting SUGAR: 88mg\dl 10. B12: 152 pg/ml I feel chest pressure and numbness around the left side regularly. Then i get panic and go to a doctor and he says everything is fine. But i strongly believe i might have something fishy in my heart which is not yet been investigated. Please suggest something. I am not able to focus in my life. I hope this fobia wont lead to heart disease. Tx and plz reply.
