Thanks for your health concerns. Sharp pain
that lasts seconds in the chest is less likely to come from the heart, and more likely to come from musculoskeletal structures such as costochondritis
or inflammation of the cartilage
of the breast bone, or esophageal causes such as spasm. It would be prudent to visit a primary care
provider to explore these differential.
Hope this helps, wish you the best
