Seek a cardiologist: It would be best to visit an urgent care center or an emergency room near you where a cardiologist can evaluate you asap and answer your concerns..

Unlikely cardiac.: Unless these symptoms are consistently related to exertion,emotional stress, not likely caused by the heart. If you have strong risk factors, always good to have evaluation and reassurance. On the whole, not strongly suggestive os a heart problem. I am not sure what you mean by “contraction pain”. Clearly useful to get evaluated and get educated on preventive measures.

Chest pain: Rule of thumb is that all chest pain be immediately evaluated. Please see your GP or Urgent Care.
