<s>[INST] I was told by a neurologist when I told him I have a small bump on my head that is getting bigger, he said it might be a cyst (even though he didn t even look at it)..and didn t even tell me what type of doctor to see to get it removed. I also read some cases online that people have actually cut the area themselves to drain it, but apparently, the cyst grows back. Can you tell me what doctor I should see. I wouldn t bother with it, but it has gotten larger since I was a teenager and it is painful. [/INST] Well...you have a swelling g on you scalp a pie full one. Scalp is a common site for a common benign swellings. It could be lipoma...sebaceous cysts ...Mets from thyroid carcinoma...Osceola...cellulitis...subaerial hematoma.you should do the basic investigation like skull x-rays and some other local test on the swelling. You should consult an experienced General Surgeon to diagnose the condition... </s>
