That sucks, calcium deficancy should make bones weaker? Don't trust me because of lack of knowledge and language.
It doesn't effect the bone much, as far as I know. It lower blood pressure since this isn't the first time.
You sure it wasn't something like anaemia? That's not caused by calcium deficiency, though. Hope your mum gets better and that you get enough rest yourself. *huggles* X
Thats rough to hear, my advice is to eat more calcium efficient food. Egg, banana, maybe chese ? , and drink milk.
