Every time I get more headaches than "normal" I go check my eyes.

For the last year I've had neck pain and terrible headaches many times a week and often the whole weekends.

Turns out it's not my eyes, it's how I sit, stand and walk. I've tried swimming(with glasses so I don't bend the neck further). Not much luck with swimming, gonna try going to the gym and exercise shoulders and my back.

The doctor applied some "body tape" to my back, shoulders and neck so I could feel in my skin if my posture was outside a normal posture. If you have headaches, try that.

Next step is to try to be aware of my posture when working, surfing and playing games. That's really hard, and I keep forgetting how I sit. :-( If you have any tips for me I'd be glad.
