Pulsating electric like feeling on my right side of chest ?

Nerve pains: If the discomfort is Sharp,shooting or fleeting and especially if it is produced or aggravated by a deep breath,cough or other chest motion, a likely cause is pinching of an intercostal nerve or muscle which runs between two ribs. This is more of a nuisance disorder and tends to resolve in a few days. If symptoms persist consult your physician for evaluation.
