dont worry too much. i think u "yit hei". last time i also like this. at first at the left side.. then at the right side. i think if u go to see doctor, they will give u antibiotic to eat. and it takes around 2 weeks to a month to heal...

if when u tekan it, the lump can move abit then u no need scare too much... if u tekan it and it wont move.. then u must worry abit lar..
