Chest pain. I have more test done?

I am having chest pain since around 3 weeks, sometimes its in left sometimes right, but i can rightly pin point it where is the pain happening, have consulted cardiologists 2-3 times, ecg,echo test were normal. But my heart palpitations have not decrease, with anxiety it increease i feel like my heart is in my hand or it.just a little beneath the skin and pounding like crazy, the pain is not continuous but i have it daily and decrease by its own, i have high cholesterol, high ldl, plus the pain is accompanied with gas, i dont know if its just heart burn or something else,should i have more test done? But the pain sometimes turn severe(happened only 2-3 times) but eases out on its own with bloating belching,i even had covid on 28 april, chest x ray was normal, i dont know if its anxiety induced,gas induced, or some heart related, but anxiety is killing me,the pain is aching if that makes sense like cramps. I am gas issue 27 april, plus continuous pulsation in abdomen (i am fat)
