Hi ,

iam 20 yr old student. Whenever I am otside the home,i feel very tired after a little work (walking/standing/studying). Due to that most of the times my knee,legs and head pains.I yawns and feel very sleepy though I usually takes the sleep of more than 6 hours.This makes me inactive and furstrated because I could not concentrate on my work. I also forget the thing soon.My friend often says me that I look very weak. But I think my weight is fine w.R.T. My height.
Please suggest me how can I get rid of these problems.

Thanks
