Hello;
welcome to HealthcareMagic
Aching in arms and legs can be due to deficiency of vitamins and calcium;and if you are anaemic so get your blood tested for anaemia and if the haemoglobin is ow then you have to start on iron supplements or tablet.Also for the pain in legs and arms at night start on some multivitamin and calcium tablets and hope fully you should feel fine in few days.
Thanks
