Hi keephurting...

All the above responses are good.

I was personally thinking of your C2/3 joint. Often when you get get headaches which affect the eye, it is this level that is responsible. Sometimes it feels like a pressure or knife in your eye.

As for the arms going numb, they are supplied by nerves which come from the nerve roots of C5-T1 but we also know from research that there are connections between the different levels of the neck discs so that even up to 3 or 4 levels away can be affected! So a C2/3 disc issue can be affecting the nerve roots of C5 and C6 and C7...which will affect your arm.

I suffer from neck pain and headaches with occasional shoulder and arm symptoms. Believe me, the best thing you can do is to seek treatment and get a good physio to check your joints, muscles, nerves and coordination (motor control) of the upper neck and back...

...this is assuming you don't have some sort of vascular problem of course Personally it doesn't sound like it to me because it is with you all the time. Sudden head movements tend to be neck or inner ear related. Sustained head positions (more than 5 seconds or more in the one position) tend to be neck or vascular issues.

Good luck and let us know how it all goes
