Right chest pain is completely possible, but according to experience, patients with right chest pain must go to the hospital, the cardiovascular slogan is to go to the hospital with chest pain, regardless of the cause, as long as the chest pain should go to the hospital so that the doctor can make a correct judgment, to see if it is heart pain or pain caused by other organs.
