[/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. It could be due to sudden hypotension (clammy skin, loss of consciousness, shaking, gasping to breath), it could have been due to dehydration, fatigue, stress, tension or anxiety. However, the chest pain and pain radiating towards the left arm are symptoms indicating some developing coronary artery disease. Get her lipid functions tests, ECG, CBC, urinalysis, test for blood sugar done to screen out any cardiac problem without delay. No worries she can be treated with medications and a better lifestyle. Give her oil free nutritious diet and regular walking should be maintained. Take care. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Nupur K. </s>
