I get chest paine like pin prick and burning in chest is it heart attack or musel paine?

Chest pain described as "burning" is often due to inflammation of the esophagus (reflux of acid from the stomach); however, it's best to see your doctor for a more thorough history and physical exam to enable a more definitive answer.

The description suggests muscle pain, but the possibility of having vital organs involved cannot be ruled out. Best to explore with your GP as to having a clear plan going forward.
