I am a female age 55, medium build, weigh 190 and I am 5' 11" tall. Recently I started noticing a strong pulse just below my rib cage, I understand that it is my abdominal aorta. Normally I understand that this is common in thin individuals, I am not thin but I am not fat either! Is this something that I should be concerned about? Just rec'd the results from a blood test, CBC and UA, all normal levels and I have always been healthy. I take no western drugs, only vitamins and herbs.
