Hi, Welcome to Health care magic forum.
She is in menarchy, and due to the changes in the harmone levels, there is every possibility of the
anxiety, and the family background also, influencing her thoughts.
The
lymph nodes can be due to the
head lice, infection of the teeth, mouth, or near tissues of the neck. More over cancer is not expected to touch her at this age.
I advise you to consult a physician for diagnosis and treatment.
I usually prescribe to my patient with such symptoms cifixime, acyclophenac sodium for relief.
Give her more of green leafy vegetables, pulses, sprouts,and
protein rich foods to counter such health problems.
Wishing for a quick and complete recovery. Thank you.
