I keep having these pains behind my eyes. They come and go. They last anywhere from 1 sec to a min, they feel like a stab or a dull ache just behind my eye. They are starting to scare me. They do not have a certain pattern and some days I will have more than others and some days I will not have any. Any help?

I'd see an opthamologist... not just a walk in glasses doc but the real deal. You might have something going on with pressure or something in the back of your eye going on.
