I feel tired all the time, at certain points random parts of my body ache and I feel weak and worn out. My hair and nails grow slow, have pale skin.

TIRED,/WEAK/WORN OUT. SEE YOUR PCP OR AN INTERNIST. YOU MAY NEED A COMPLETE EXAMINATION PLUS BLOOD AND OTHER LABORATORY INFORMATION. HOW LONG HAS THIS BEEN GOING ON? DON'T WAIT . . .
