In case you don't know why, here's the reason:

I told the doctor about the lump. He looked at it and say it's a
minor one. He said there is no need to drain the pus out and
prescribed me some antibiotics. He said if it doesn't get better, I
have to come back to see him.
In the end, I paid $50 for the consultation and 3 different type
of medicines: Anarex for pain/fever -20 tabs, Augmentin as the
antibiotic -10 tabs and Korzen for swelling/inflammation/phlegm-20
tabs.
When I made the payment, the receptionist told me the
antibiotics is expensive. I don't know why she told me. Overall, I
felt like I being ripped off. And it seems the article I read last
time really prove me right, doctor prescribe antibiotics to solve
the problems.
