[|Human|] I was at a 5K walk this morning and had a sharp pain in the left side of my chest followed by a metallic taste on the left side of my teeth and mouth.  The chest pain went away within 30 seconds and the taste dissipated over a few hours.  I am a 40 year-old, 59, weigh 125-130 lbs. woman.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. You are having left sided chest pain on exertion. This is characteristic of cardiac diseases. So better to first get done ECG and 2d echo. If both are normal than no need to worry about heart diseases. Muscular spasm due to exercise can also cause similar symptoms. So avoid stress and tension. Avoid heavyweight lifting and strenuous exercise. Avoid movements causing pain. Start painkiller and muscle relaxant Chat Doctor.  Apply warm water pad on affected areas. Don't worry, you will be alright. But first rule out cardiac cause. Hope I have solved your query. Wish you good health. Thanks.
