Hello, I am 16 years old and I have notice for quite a while (over a year) my hands shake. Its very noticeable when im holding something for example a glass of water, my phone even a pencil. I then have recently found a hard bump directly on the back of my head. It does hurt to push on but its been over a month. It is now that people notice my shaking im not able to hide it but it is quite embarrassing. I just dont want to sound crazy and go see a doctor yet. Can any one help on here?
