Hcq side effect for corona. Suggest!

Hello sir, I got Palpitations and sweating on the left hand after taking HCQ 400 one tablet, next day took azithromycin and got stiffness and heart stopping feeling. Got scared went to hospital and joined for corona treatment got PACs on ecg, but the second ecg they took was normal, they gave me medicines like telma40 and metosartan50 and normal protocol for covid during my admission for five days, I was actually asymptomatic with corad- 1 and went to hospital out of fear. Now it's been 8 months I'm getting thuds in left chest while lying down which is changing with emotions and mindset, doctor says it's anxiety, I feel perfectly normal except these thuds and mild muscle pain near the ribs and shoulder used to have more but went away on its own, one day is good other day not so good, what should I do, heart rate, bp are normal. Please suggest
