Unclear: Based on limited history it is hard to give any advice except see your MD. Any problem that hangs around this long needs to have a good checkup. You list heart disease in family but at your age it's very unusual for that to be the cause. Make sure you are taking a multivitamin as many teens don't eat balanced and lack of certain minerals can cause muscle fatigue. Drink lots of water - c MD soon
