It is hard to say exactly what is causing the sharp pain that you describe. You can request an ECG and ab X-ray image of the chest to exclude possible lung, heart or bone disorders. At your age, however, anxiety is also frequent reason for such pains. You can consult your GP about for an expert opinion and advice.
