Your complaints are fatigue, joint pains
, nausea, headache, tiredness
and flushed face. You are having a history of palpitation
for the last 1 week. You have not mentioned your age.

has to be ruled out. If you are aged ECG should be taken. So Consulting a physician is the only choice. He will investigate and treat you.
