I was just told i have costochondritis separation. will this make me have more heart palpitations then normal?

Costochondral: Check with your doc. Costochondral problems should not cause palpitations.

Palpitations: Palpitations have many causes from anxiety through anatomic and physiologic abnormalities. The feeling of bounding usually relates to the volume of blood pumped with each palpitation. There is no simple single answer for the question. If you're bothered by the feeling should consult a dr. To see if the problem can be clarified.
