I felt induce tachycardia and mild chest pain when im on workout after a month off with it. is it angina? or is it normal uncondition for workout?

Maybe: Any exercise induced chest pain should be evaluated by a medical professional before further heavy exercise. In young people the risk of coronary artery disease is relatively low, but it is not zero, especially in the setting of major risk factors like diabetes or smoking.

Maybe: Doubtful you have coronary disease at 29, but nothing is impossible. May be a bit exaggerated for only one month without exercise - unless had been bed-ridden. Many other causes as well, dehydration, acid reflux, pulmonary emboli, ... As will all chest pain - if in doubt, best to have it checked out at least once. Hard to say without ecg, further history, and perhaps additional tests.
