Not enough info, but: Whenever left, chest, tightness are said - I'd advise an exam. No, you should not worry since that would only make it worse. But anyone who exercises should have a good exam to help determine the appropriate types and levels to start at and rates to progress at. Your BMI and history and many other details will matter for planning your best routine. Best!
