Why is my left arm numb?

I went out and drank a few (nine) drinks last night and it was fun. So fun that I forgot to eat dinner.

Upon waking up (late) this morning, I was hit by the "Jack Daniels Gut-Rot" coupled with intense starvation. I rushed through a shower and out the door, ran to the subway, caught my train - then as I was walking by McDonald's I was captivated by the poster for the Country Breakfast Burrito ....bacon, eggs, hash browns, AND cheese all rolled conveniently into a nice utensil-free meal. Anyone who know's me knows that I am eternally devoted to the breakfast burrito, so......I went for it.

It was f'n delicious but I think I'm having a heart attack.
