<s>[INST] im 22 y/o athletic healthy excercise everyday for 2 hours i am now having chest pains n tightness at random times of day n mostly at night when laying down also feels like someone has there hands around my heart and are squeezing it feel like someones sitting on my chest all i take is whey protien daily after workout and i eat healthy...should i be worried or consult my physician [/INST] Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of stress and anxiety related chest tightness and pressure is more. But better to first rule out heart related diseases. So get done ECG and 2d echo. If both these are normal then no need to worry about heart diseases. Sometimes uncontrolled stress and anxiety can cause similar symptoms. So consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor.  Don't worry, you will be alright. Avoid stress and tension, be relaxed and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
