59 yr old female; reasonably athletic (weight lift, walk 5 miles 4x week). Have been experiencing almost immediate onset of pain in calves, shortness of breath, tight feeling in throat as I begin to walk briskly or exert a bit. EKG / ultrasound shows moderate problem with a heart valve. How concerned should I be? taking extra vitamin E as heard it helps circulation for the leg issue. This just isn t right and I worry about keeping myself going.
