Itchy Scratchy

I really wonder what happen this evening.. After watching Transformers at The Cathay, I was scratching all over.. My whole body was itching like mad, but I had to control myself, couldn't scratch too open in public. But hell, the itch was super unbearable, almost got mad with it.

Upon reaching home, woohoo, eased the itch by scratching like a dog..

But now I really wonder why am I scratching all over? could be a few reasons.

1) the dinner I ate at Tam Po Po - maybe allergic to some food item like the fish roe

2) the seat at The Cathay - which is not quite possible as my back wasn't itching, just the front and the neck.

3) normal heat rash

Grr.. the itch is still super unbearable..
