Lymph nodes

Now I am seriously concerned about my right lymph node on my neck. I have finished 2 courses of antibiotics which would supposedly have brought it down (just after one course would have sufficed apparently) and it's still slightly swollen! Though it's not as bad as before, the fact it's still there bothers me! I have asked my doctor before what I should do if it doesn't subside and he says 'don't worry, usually a course of antibiotics will fix this'. I was doubtful and asked 'what if it die die won't go down?' He actually paused and said 'Well I guess I can refer you to a specialist who will then do a biopsy by sticking a needle it and draining out the lymph fluid to see what is inside.'. He then scribbled some stuff on my medical card and said 'Usually by the time the patient sees the specialist, the node would have subsided'. He says in the WORST case scenario, it could be harmful and can either be drained out entirely, or cut out! But he promises that that is generally quite rare.

ARGH! That was my SG doctor who I trust somemore. I saw 3 other HK doctors (for varying reasons) for the past few months and none of them think this is cause for concern! 'A swollen lymph node shows that your immune system is working!' says one.

But it's been so long!! It really bothers me! :(
