<human>: I am a 14 year old girl with a history of unexplained medical issues. I am 5 5 and 120 pounds. Recently I have had shortness of breath along with chest pain around my rib cage. My abdomen has been rather uncomfortable with some pain as well. I have been slightly nauseous, and have started having night sweats about every other night. Also have been itching all over my body. Any answers?
<bot>: Hello! Welcome and thank you for asking on Chat Doctor! I passed carefully through your question and would explain that it is necessary performing a comprehensive differential diagnosis between different possible causes that may lead to this clinical scenario: a lung disorder, an allergic reaction, a metabolic disorder, an infection, etc.  Coming to this point, I would recommend consulting with your attending physician for a careful physical exam and some tests: - a resting ECG- a chest X-ray study and pulmonary function tests-complete blood count, PCR, ESR for inflammation- thyroid hormone levels for thyroid dysfunction- blood electrolytes- an abdominal ultrasound- a urinalysis - allergy tests. You should discuss with your doctor on the above issues. Hope you will find this answer helpful! Kind regards,
