Do I have have brain cancer?

Hi, I'm a 20 year old male. Im worried to death, I feel like if something is up in my head. It started like 5 days ago, I had some kind of weird pressure feeling on my right side of the head, when I mildly tapped my head, I would feel this strange feeling on my right side of the head. Right now, I dont have any migraine type headache, or some strong pain on my head, but it definitely feels strange. I have this sudden mild sharp pains on left and right side of my head, I feel a bit disoriented, like if Im going through the motions. I suffer from what I think is sudden panic attacks, I get this feeling of passing out, like if im dying, but just minutes later im all good. Like yesterday I got this burning sensation running across my neck and left arm, I felt like if I was passing out, and my toungue went numb. If had a hand full of these attacks, so now I kind of control them better. Sometimes it feels so real, that I cant control it much. I dont know if that has to do with my head's feeling. I also have sudden ear pains. Any help will be much appreciated, thanks in advance.

Given the low incidence of brain tumours it is most unlikely. I have one so understand the symptoms. I suggest you consult a healthcare professional and be reassured about what is happening. 

Im now having complex tics, I dont think ive had then before. Sigh, all over again, about a year ago I was so convinced, 100% sure I had pancreatic cancer. Now this

I suggest you to consult a neurologist, there may be some problems with your neuronsattached to your brain.
