oh and I forgot to mention that chest pain and shortness of breath are the classic symptoms of hyperventilation, it can be extremely scary for the person, but you just have to remind them that they are not going to be affected by it
She can very well be hyperventilating or having an anxiety attack. Hyperventilation is where you breath too much and your oxygen level is too high. This is nothing to worry about, it is 0 % life threatening or at all physically threatening. A psychologist can help you out with this, good luck and God Bless.
hi, it could be from muscle or bone, from the lungs, or even from the stomach
