More than likely, it isn't a brain tumor. I mean, I guess it 'could' be and you could always get a catscan, as it would probably ease a lot of your discomfort, should you not have one.
I have had migraines for years. They burn so badly that, at times, I can barely walk. My heart would beat fast, feeling as if it were going to implode. Sometimes they lasted for days, ruining my life.
I had done all sorts of research about headaches, finding every possible reason, other than a brain tumor, as to why I had them every day. I didn't drink enough water, or I didn't eat in time, or I slept wrong, or it was allergies....it was always something.
Finally, two months ago, I couldn't take it anymore. I had it set in my mind that I had a brain tumor. I even started believing that I was becoming psychic and upon watching the movie "Phenomenon", I made a decision that I had a tumor growing inside my head. LOL, it was absurd. I also have had impacted wisdom teeth for a year that I have not been able to afford getting out, in which that was my reason, in my mind, that the tumor started. I had read somewhere that impacted wisdom teeth (rarely) can cause a tumor.
So, one day, after a week of a headache, raw nerves, racing heartbeats, panic...you name it - my legs, feet, head and fingers kept tingling and would not stop. It was on the left side, none the less, making my thoughts think more and more negatively. I thought I was going to have a stroke - either that, or some weird infection from my head was going to go to my heart (I have a heart murmur, for real - haha). I live out in the country, and my boyfriend would not take me to the ER. He said I was not dying and was fine - to calm down. I have no insurance and I think he was trying to think rationally for me, as I obviously, wasn't. After hours of crying, and my attempt to hitchhike to the ER, he finally took me.
I had a catscan done and it was perfectly fine. It was clean. I felt like I was going insane. I asked the doctor why I had the exact symptoms of having a brain tumor and he said the mind is a powerful, powerful thing - along with stress, combined with that - was the reason. He said, "Now, if you could only use your mind power towards positive things, not negative, think of what you could do"!
My father has a horrible history with headaches, in which they can be passed down if it is the family history. Not to mention, I have horrible allergies, wisdom teeth issues....etc.
The thing is, I could SWEAR that the doctor was wrong and he missed something. I don't have insurance and didn't even care - I just wanted to be checked into the hospital, examined for everything, in order to feel "safe". No one could tell me anything, as I would not believe them.
It is scary and I completely understand what you are going through. If it makes you feel better to get a catscan, have second opinions, etc....so be it. You have to do what you need to do, for your sanity.
It sounds like you have SO many issues and stresses in your life - you need to find something that you can relate to or turn to, that eases your discomfort. I started walking on a treadmill to alleviate a lot of pent up stress and it help tremendously. Do something simple, but different - something that makes you feel better, no matter how minor it is. You will be proud of yourself and maybe start to alleviate a lot of the negative thoughts and stress.
Also, I have been on Paxil for a month, and less "nervous" and have had a headache ONCE for three days and even then, I think it was due to "that time of the month". Since I have felt a bit more "safe", the headaches that I had every day, have subsided.
Good luck, dear,
