<s>[INST] i was working in a electrical panel when a maintenance man thought it would be funny to scare the crap out of me!five minutes after calming down another maintenance man did the same thing yelling hey as loud as he could.now two entire weeks my chest still hurts and for some reason my legs still feel like rubber.i have a echo scheduled for the 30 th.what do you can be wrong. [/INST] Hi Thereafter going through the details u have provided it doesn't seem like you have a cardiac problem but to be completely sure get your echocardiography as well as an ECG done. To me it seems more like a psychological thing , so once your basic cardiac test are done do consult a psychologist for your moral boost.  Good Luck </s>
