Hi, welcome to Health care magic forum.
It appears that she is having
hysteria,a functional problem due to the some problem in the life, may be the head ache,or a tensions in the life.
I advise you to show her to a
psychologist for diagnosis. The patients with such problem may drive into a psychological problems.
She may need medicines, counseling,and if the doctor feels,may require the
shock treatment.
Ask her to take more of green leafy vegetables, pulses, sprouts, and protein rich foods to have blood,general health and resistance against infections.
Wishing for a quick and complete recovery. Thank you.
