Eye Presure Stiff Nech and Randomly Moving Pains, Whats up?

Hello Iam Eric and, Around Christmas I started to get a headache around the top of my head and the back of my head, Since then it seems to have gotten better But I am still worried as I have had alot of Bumps and Hits to my head over the years... Iam 15 and I have a fairly good health, that i know of. Since Christmas the headache has gone away but now every now and then i get a sligth paint on the bridge of my noes near my eyebrows on either the left or right side, it switchs randomly from day to day. I am also experiencing Stiffness in my neck, I also have some Fat Growth of my head, but my doctor said its on the outside of my skull so it cant be the cause of the head pains, Recently a found several Small and i mean small bumps on my neck, imbeded in the muscle, I was poking around my neck to try and find whats stiffening it up, and i found these little bumps, they feel about the size of one of the grapes that didnt quite grow, you know the really small sour ones :-P. I just want to make sure that theirs nothing wrong with me... do i mabye need glass's? also I dont think this could be connected to my neck and eyes but every now and then I get a slight presure in my left or right arm, also switching randomly. When the headaches first started it felt like people were jabbing the back of my eyes with needles now, it dosent really hurt its more of a nusanse, now its feels like somthings beside my eybrows but i know theres nothing there, just muscle. Anyways I know of rambled For a long while iam just concernd about these sorta things, a friend died recently of Cancer behind the eye, and its been bothering me ever since.

Eric. Any explenations for any of the symptomes would be great, also stiffness in the neck seems to be on the left side only, no loss of feeling in any limbs or anything like that.
