There might be a number of factors contributing to your fatigue, but one that should be investigated is your vitamin D status.
A deficiency of vitamin D has been linked to muscular cramps and weakness. Children and the elderly also showed symptoms of this illness, therefore it clearly does not have an age-related basis.

Vitamin D promotes hair growth by shifting it out of its dormant period. The vitamin was severely deficient in a large percentage of alopecia-stricken females.
