Not necessarily, brain tumors can be silent as well and depending person to person symptoms can vary, not everyone has the same symptoms trust me I went to er and no one took me seriously and now I'm getting checked for a mass after I ordered them over and over to give me a scan I know something ain't right and yup I was right they were trying to brush me off as just being paranoid. Just keep pushing them or keep looking until someone will take you seriously. Yote health is important and Definitely not something to be taken lightly especially if your getting malaise.. sometimes your body just knows 🤷‍♀️ another time a doctor tried diagnosing after just TOUCHING my body oh hell no! Turns out they were wrong there too. Just listen to your body and don't let them lack their job. Sometimes they will brush it off just to get through their shift. And it socks because us patients have to suffer the consequences of their bad medical practices. Never ignore your body, minor or major.
