I have two lumps in the back of my head (no not the bumps that appear naturally in certain spots). I suspect theres possibly one near my sinuses too. My personality has changed in the past year - like Im a lot more callous,without meaning to be. If i look up too long, i get dizzy. If i move around a lot, i get migraines. My heart sporadically contracts. My nose never stops running even when im not sick but i have no infection. My memory is getting worse to the point i apparently said bye to my roommate when they left the other day but thought they were still getting ready to leave 10 minutes later. My appetite is all over the place. Im almost always tired i alsobave depression. I have a really hard time showing emotion, or sometimes feeling it, which is new. Things will randomly get blurrier than normal, and my eyesight has gotten noticeably worse in the past year. Im always angry for no reason. I sporadically just have emotional swings put of nowhere and want to die but not in a depression sort of way, more an outburst of anger (no im not bipolar). I forget things i should be able to remember and sometimes just zone out because i get confused and my brain just feels like it gave up. Had a severe TBI (open head) before like from 4 years ago. These symptoms showed a year ago but not the dizziness it was from a month ago. The headaches some get in the morning but most headaches are when I move. No sizures of any sort. So is this an aftermath of the TBI or a tumor? and what should be done to get the buttom of this I mean MRI or CT scan or tests and what is the possible causes of these symptoms.
