I've been getting headaches for as long as I can remember, even when I was a child. I've been told multiple reasons, from changing spectacle numbers to chronic sinus to stress headaches. Lately they've been getting worse. I feel pressure in my temple and behind my eyes. It makes me slightly nauseous too. Sometimes my entire crown area hurts like I'm wearing a really tight headband. Taking disprins has always helped but I've realised that's not a solution. Looking at phone or laptop screen during that period is almost impossible. The internet tells me what doctors have always told me plus migraine as a possibility. I just want to know what's the easiest way I can get a single accurate diagnosis so I can actually focus on that single treatment. Oh and I also get these headaches if I'm out in the sun for too long.
