A member asked:

My sister has been complaining about feeling her heart beat on her left side right below her armpit. she says it feels like a muscle spasm not a heart?

Dr. John Chiu answered

See doctor: Muscle spasm does not pound like a heart beat. It is likely nothing serious but still requires a medical examination to be sure.
