Twitching in upper side of chest (right side) like close to the middle lasted for like a minute and went away no other symptoms what could this be?

May be nothing: What you described does not seem to be a matter for concern. If the symptoms recur more than twice, see a doctor. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine

Possibilities: Brief twitching of a muscle can be caused by abnormal levels of phosphorus and potassium calcium magnesium . The buildup of lactic acid caused by prolonged exercise of a muscle without relaxation can also cause this.Brief twitching of muscles is usually benign. Persistent twitching should be evaluated by a physician
