Thanks for query,
It seems you have got generalized weakness causing all these vague complains.
As all reports are normal so you do not worry,
You might have anemia
and multivitamin deficiency
Go for blood for Hb,
Take nourishing high protein diet,more milk,green veges,fresh fruits.
Take Iron tablet and multivitamin supplements,calcium and trace elements of zinc etc.
ok and bye.
