She needs to see a physician. Keep nagging her and convince her she need to go. It may or may not be serious. Either way she needs to see a doctor.
M son is having same symtoms and he went to see doctor this morning and they couldnt find any reason for his aliment.....so mom that i am i asked him thses following questions
1: last time he had a bowel movement?
2: how much water is he in taking?
3: has he been eating and what has he been eating?
i asked these questions because if the body lacks sufficient water, proper foods and lack of rest, the headaches can occur......( just a few reasons for the headaches)
if his eating habbits are poor, this can cause the fatigueness
the chest pains he is having can be caused by a type of stress on the body
and sometimes when you havent had proper bowel movements, you can become very nauseated
so for my son i am administering moms healing regimen......................
love, food, water, and persistant encouragemnt to rest
