i m feeling a weird pain underneath my left breast . not inside it, inside my chest but i don t think it s my heart . my heart is beating normally and nothing hurts when i touch the area around this pain. i ve felt it before in the past but it only lasts on and off for about ten minutes and then it goes away. tonight it is bothering me a bit longer than usual and i just want to know if i should be worried or not. it feels like it is under my breast but lower than my heart. and it doesn t hurt, so much as it is a dull ache as if it is an aching muscle that needs to be stretched
