Why is my sisters body aching every night?

[RUNFORLOVE]

For the last few weeks my sister said that every evening her body aches all over and sh eeven finds it hard climbing the stairs to bed.She said muscles and bones hurt. At first she thougth she was coming down with the flu but the next morning she felt fine. It comes on mainly at night but can come in the day?

What could it be?

She is fit and healthy and is breastfeeding her 9 montn old. I am not sure if maybe she not eating enough for the demands on her body and maybe she is lacking in certain vitamins. Could this be the case? Would that make you ache?

I have told her to go to her gp but any advice or experience would be appreciated.

Thank you

Could be low iron, she could ask GP for some iron tablets. i felt tlike this during pregnancy and turned out i was aneamic.

also thyroid levels, when i went hypothyroid i was so fatigues ta end of day it hurt. mind you was also almost as tired after 10 hours sleep!
