It's made me completely heartless, i used to be a real nice person who actually cared about people, Not anymore i could give a **** less what happens to anyone

What do you mean weird head sensation?
Are you reffering to feeling disconnected?
Out of it?

If you have had every test there is to show that you do not have cancer or an illness from that, perhaps you're suffering from anxiety? Worrying the worst possible outcome with this?

Do you feel like you could faint if the sensation became any more intense? I've been having something similar. Since I've suffered from trypanophobia (fear of needles, injections, having blood drawn, etc. and subsequently fainting at being poked or the mere mention of being poked), I've wondered if my sensation, at least, might be a brief drop in blood pressure due to some irregularity in the functioning of my vagus nerve. This can affect heart-rate and/or blood vessel dilation and maybe lead to strange sensations in the head. And the trigger list is pretty extensive.

Yes, this describes the more obvious "fainting" spells caused by vagus nerve behaving badly, but a "lighter" version of this response could certainly explain weird sensations in the head. Recent work (in the last 10 years or so) has show that there may be links between depression, anxiety, and the proper functioning of this nerve.

Some of the meditation exercises might prove helpful for relieving your strange head feelings (if they are indeed the result of slightly abnormal blood flow). Engaging in physical activity could eliminate the effects (during the course of activity... afterward, you're kinda on your own) as should drinking sports drinks that increase blood volume.

Just a possibility...

I have a strange sensation too. It's like a burning numbness sensation. Not burning. I feel VERY disconnected. i feel dumb. School starts in a week and I'm kinda scaerd that my grades are gunna plumbet and I'm gunna end up at the pizzeria I work at for the rest of my life. That might be a phobia that might be anxiety... anyway what does the sensation fel like? kinda like what I described? because I have anxiety big time. Never been diagnosed but before I researche online I described the way i felt to my mom, and when I loked it up online it matched perfect. Sorry to explain the way I feel on your topic. But if this sounds familiar maybe you have anxiety.
