If i'm having slight chest discomfort simultaneously on both sides of my chest lasting less than 5 seconds is that something to worry about?

Maybe bad: So not all chest pain is bad, not all chest pain is a heart attack, there are many other causes of chest pain and generally chest pain that lasts greater than a few moments is more concerning than what you describe. Also if it only happens once versus episodically or continuously. Bring this to the attention of a provider if it’s happening more than a single occurrence.
