Had no idea what bit me but when I woke up the day before yesterday
morning, it was very, very itchy and after a few hours, it began to
swell and hurts when I move my hand too much. Luckily the pain subsided
after I applied Tiger Balm (a type of ointment) so that I am able to
take notes during lectures. But the pain came back yesterday and the
swell became bigger and more pronounced so after advices from my
friends, I went and see the doctor. He gave me a few tablets for the
pain and itch and a cream to rub for the swellings. Now it is much
better but it still itches~ Grr~

PS: I am so going to kill the bed-bugs, blood-sucking mozzies, big ugly bee stings etc if I find any of them in my room tonight
