Veins/Arteries on sides of head

I noticed last night during one of my tension (band around the head) headaches, my veins were clearly visible and swollen.  This has since gone away, but Temporal Arteritis comes to mind (because I have had blurry vision at times too).  Does anyone know if veins that look like Temporal Arteritis come and go, or are they just always swollen looking? 
Thanks
