### input:
Approximately two years ago I felt a slight itch on my scalp near the crown gave it a scratch thought nothing of it. Within 24hrs a small painful lump developed at the site. I worked outside with old transport tires picking up/delivering probably mosquito it will go away. It did not and it became larger more painful very itchy. Went to my Doctor who could not feel it told me to return in two weeks if there was no change.The lump felt like half a golfball and the entire right side of my scalp became inflamed underneath. And yes I returned every two weeks for 4 or 5 appointments until she consented to an ultrasound the tech found it instantly and yes he said there was definitely something there. The doctor said she did know what it was and that it may return. The scalp on the right side now has ridges the other side does not and the lump did recede. But my memory is impaired and my balance and spatial awareness is also off. What do I do?

DearWelcome to ChatDoctorWe understand your concerns went through your details. Your brain is covered with a solid skull which never permit any sort of contaminants into your brain. Whatever affected your scalp skin or the area between skin and skull, could never infect your brain. In that case, your loss of impaired memory, loss of balance or spatial awareness (if it is true) cannot be attributed to the lump or further scenarios. I suggest you to consult a neurologist at the earliest for treatment.  If you require more of my help in this aspect, please use this URL. http://goo.gl/aYW2pR.
