I've been having this slight pain in my left chest for the past three days and it's starting to worry me. What should I do?

This chest pain could be due to various reasons, including muscle strain, acid reflux, or even heart-related issues. However, it's important to rule out any serious conditions. I recommend taking an over-the-counter pain reliever like acetaminophen (Tylenol) for relief. If the pain persists or worsens, it is advisable to consult a healthcare professional for further evaluation and appropriate management.
