There is history of lifting heavy weight by your daughter. After that she started having chest pain
on left side and in left arms.
If chest pain is due to weight lifting ; it will subside within a day or two if pain killer tablets and gel is taken like diclofenac
But if the underlying cause is heart; then chest pain will persist and will increase on exertion and relieved by rest. In this case consult physician and get ECG [electrocardiography] done. Sometimes exercise treadmill test might be advised. If chest pain still continues then enzymes need to be evaluated to rule out Myocardial infarction
