Hello @juliar19, welcome to Connect. The type of electric shocks you describe are scary as you know what. Thankfully, your heart tests proved negative. I have not had a baby for 21 years, but do remember the stress and anxiety that accompanies the life changes.

Although we are not medical professionals here on Connect and help through our own personal experiences, I agree with @sueinmn that reducing anxiety is a healthy focus and easily could be a culprit.

My chest pain and electric shocks happened as you describe, under the breast almost in the rib cage area, and center of the chest. They often happened while I was at work and came out of nowhere. Life was super busy then, having 2 kids a job and all that comes with it. I remember thinking the pain and discomfort may not have been normal, but I was always able to slowly breath my way out of them. Then I'd commence on feeling a short-lived dull ache where they happened. For me, it was all nerve pain. Stress induced, no doubt.

I'm glad you have a follow-up with the cardiologist, and hopefully you'll stay connected with your PCP and see what they have to offer. In the meantime stress-management tools such as progressive muscle relaxation, diaphragmatic breathing, mindful meditation can all help. Here is a quick easy way to get started -

How are your nights going? Are you getting adequate sleep yet? Sleep can also be a contributing factor as can poor diet. How do you feel you are doing overall with self-care?
