I never feel this much pain...

I...I....*runs away*

Pain killers? I don't know all I can say is go to the doctor. Chest pain often indicates a 심장 problem it sounds pretty serious so 당신 should see a doctor soon.

Not everyone here would know the cause for this so....

I'd say you're in a bit of a depression 또는 possibly are suffering from some sort of crash in health due to stress 또는 anxiety that has accumulated in your life.

Take some deep breathes, get away from whatever's bugging you. A nice walk while listening to 음악 당신 like might help; fresh air is 더 많이 beneficial than one thinks.

Use a little Morphine...

Wow, sounds like 당신 have a motor neurone disease......well, there is no cure :/
I could suggest Bicom therapy, but they may not have it where 당신 live. The only reason I say Bicom, is because I have first hand experiences with it, and it is very effective. Weather it can cure something as bad as that, I don't know. Why haven't 당신 heard of it? Doctors are too sceptical, and don't believe in it. But me, my family, and my 프렌즈 have all had brilliant results.

Well, 당신 know what they say: 'An 사과, 애플 a 일 keeps the doctor away, but a doctor per emergency keeps the Grim Reapers at bay."
...Dude, go tothe frakking doctor!
