Bounding pulse 24/7. There all the time?

I was covid positive in july 2020.. since then all symptoms and issues started.. my reports including blood work, vit d, vit b12, thyroid, bp, HBA1C is 5.9, ecg, 2d echo are normal except for urine which says there is bacteria.. I have bounding pulse 24/7 since 10 months.. I feel my head shaking or bobbing, chest pain every day, tremors in hands, pulsation in neck on the tonsils.. it's more evident while I lie down.. I can also feel tat my phone is moving in the rythm of my bounding pulse.. I don't know how to get back to normal life but this is bothering and I'm feelimg sick to the core.. I somehow feel tat the docs are Missing some aspect or being misdiagnosed cause my symptoms are not going away.. If palpitations will I have 24/7? If yes, then why is deep breathing not helping me relieve symptoms? Why is it there all the time?
