question: HI - i am female , 46 years old. fairly fit and run regularly. i have had no issues with health and my screenings are all clear. I am under a little bit a stress currently due to some personal issues but other than that,. nothing unusual. Recently , i noticed a very mild throb in my chest which has been consistent for the last week. Not really painful but it is there. ( very slightly to the left of the central chest area ). Anything to be concerned about ?
