You sound very similar to me, but I don't get dizzy. My headaches are very similar to yours it seems like, I have been able to tolerate mine. I've been to an eye doctor and my GP and neither of them even thought tumor, the only reason they talk to me about it is because I brought it up. My head pains have been going on for three months now. My doctor said he might send me to a neuro not because he thinks it's a tumor but just to make sure something else isn't going on. This all started when I had anxiety issues, now I focus on every single ache and pain and probably magnify the severity. My headaches aren't debilitating but just annoying, sometimes they are in the front of my head other times on top or the back. I still am concerned that something is wrong with me but day by day I'm calming my self down and I can feel my self getting back to the old me. two weeks ago for about two weeks straight I had a feeling in my head like it had been stuffed with something and that nothing was going on in my brain, This was the scariest thing I've ever experienced, It did eventually go away. I've had body aches, twitches, heck there was a period of time where four days straight I woke up with my whole body shaking, I woke up with a numb arm and face for about a week, I get occasional stabs of pain in my head(these are referred to Ice Pick headaches and are benign, but very annoying), I've felt like my concentration and focus has been off but when I work out I'm a sharp as a tac. I also go to the gym everyday and am a year younger then you. Those eye and neuro test are pretty darn effective when it comes to eliminating brain tumor as the cause for issues, I have heard that 90% of tumors are suspected and found because of a bad eye exam that lead to further testing, and someone who is no longer on the forum had two family members with brain tumors and they failed their neuro exam. Things that come an go are often a good sign that it isn't something sinister. I'm not trying to he harsh, and I am certainly not diminishing your symptoms because just like they are with me, they are very real and very unfortunate. I posted to let you know that you aren't alone and it appears someone else had symptoms like us, got tested and was clean.
