I have been having symptoms of extreme tiredness and achiness. My skin feels soar and bruised underneath, that's probably my muscles. Also when I go outside , As soon as I'm in the sun it makes me feel sick and instantly tired. Are all these symptoms related? If not what could be wrong?

You shuold really see a doctor about this. Also there is a good website that might be able to help you, its WebMD - Better information. Better health. (http://www.webmd.com) check it out. There is a spot there where you can put in your symptoms and they can help steer you in the right direction. I hope your feeling better. I know that Web Site helped me out a couple of times. But you should still go and see your Doctor.
