Hello i'am 19 years old and for a little while now have been feeling disorientated feelings in my head. Now its like not like a normal headache because it doesnt set in my head like a normal headache will but it will start fo rinstance on the back left side of my head and sometimes move around. It I will move to the top of my ears and give it a funny tingling feeling and sometimes into my cheeks and gums. And what bothers me most is , how it shoots down to the rightside of my neck and into my left arm and sometimes down to my left foot. Before this whole new head feeling crap ive been experiencing I was feeling pressure on the left breastbone area and after being convinced I was going into cardiac arrest I went to the er and the doctor said my heart sounded great and didnt even say xrays were necessary. So ive forgot about that pain and ignore it whenever it happens but rarely does happen now. Ive just been stuck on this head thing. Can it be a brain tumor? Or an aneurism? Or is it anxiety? Id appreciate any input or opinions. And please dont say go to a doctor I hate that response I will but not nothing serious has happened to me at all from any of this.
