what happen to my body?

Im not good at all these few days...
had chest pain since yesterday...
dunno whats the cause also...
went to island hospital alone to seek for doctor...
spent me rm75 n just telling me that i have low possibility to get heart attack or lung disease those stuff...
maybe just stress or muscle pain...
no medicine for me...
maybe i should feel relief that i dont have to take medicine...
but it seems like getting worse after the consultation...
hopefully it will disappear when i wake up tmr....
i really dont wanna go n do check up... ECG n X-rays those stuff sounds really horrible to me....
i just wanna be healthy...
i dont hope anything goes wrong in my body....
im not really greedy right?
can u stop the pain?
