I've been having brain tumor symptoms for 3 years now. Im 18 years old. Do you think it would've been diagnosed already? I am the biggest hypochondriac but I have some weird symptoms. In 2009 I found out I had a lazy eye (doesn't move or anything) but I can only see 24% it was only diagnosed as I had visited the optometrist due to killer headaches.. Thinking my eye sight was the cause. This was not the case. Through visiting numerous eye specialists and optometrists my eyes are healthy. However, i think i have brain tumor. My arms shake especially my left, my friend even noticed it the other day whilst a dancing (its like a shivering shake) however, i still managed to do two hours of dancing. My leg also just randomly jumps usually when I'm laying down. Idk it's weird to explain but when it happens my leg just jumps. It's not that painful.. I do get headaches. I don't vomit at all and my headaches don't wake me up at night. My balance seems to be ok. However, i find it pretty strange how I have a lazy right eye, my right leg jumps and my right arm shakes.. The left side of my body hardly does. I have a pretty active lifestyle, i do dancing five times a week, Aswell as the gym. what do you think?
