I feel pulsations in body (bp 135/65)

Please read fully😔 Hi,I'm a 17 year old male, quite fit. i feel pulsations in my body which come every time my heart beats. It has been happening since lockdown.. One day i worked out a lot, got a little ill... Thought i had covid.. It was nothing... But since then my heart started beating forcefully... My sleeping was difficult.. I i felt every beat as my blood pressure was 140/60...tried petril  beta10 for first week... Nothing helped... Then i suffered with these symptoms for 2 months. Then i went for homeopathy... They gave me kali phos... It reduced the anxiety and symptoms a lot (50%). Still i feel the pulsations when i sit still... My bp is still around 135/65 when i am calm... I just want to get normal as i used to be... I exercise regularly... What should i do to end this and get the 120/80 bp like when it used to be. This feeling of pulsations is disturbing and interferes in my day to day tasks like studying etc. Cant focus please help.
