My age is 26yrs ,last year in May I got Covid-19 and with self isolation I recovered completely later I got panic attack I undergone physchiatric counseling for 3 months now am very good but while at sleep during day and sometimes at night am waking up with palpitations and it goes for some time .I observed that when am starting exercise routine am facing the issue ,so my question is that is exercise causing me heart palpitations and any theory that suggests the same. Note: palpitations occurs only for sometime and no shortness of breathe, chest pain observed .
