Chest pain. Again? what is the solution?

I feel chest pain,discomfort,sometimes  palpitition type of feeling for several months, especially in the left chest, occasionally on the right. It happens even at rest& while i get tensed or hear high bass sound. Bp 105-112/ 65-75, pulse rate around 57 bpm at rest and increased on activity. Ecg normal sinus rhythm, echo normal with EF= 61%, TMT Positive but CT CAG was normal with zero calcium score in 2023, moreover normal coronary angiogram report with slow flow.( 21/12/2024). I have reports of Hs-crp 0.28, ldl 55, hdl 57, tg 40, apoA1 143, apoB 47, hbA1c 5.6 done june '26. Normal halter monitoring for 48 hrs 6 months back. My questions : Is it a serious heart related issue? If yes,  how severe could it be? Do i need another coronary angiogram again? What is the solution? I am a non-smoker and non alcoholic.
