I'm getting frequent pain above my left eye, which spreads to the left side of my head, and it's really bothering me. The only thing that seems to help is sleeping. It tends to happen for any reason, but I particularly notice it if I've slept too much or spent a long time outside on a hot day. I used to have more headaches when I was younger, like till around 14, but they stopped and now it's happening again. The pain is usually mild when I wake up, but by night, it's unbearable. I'm curious what's going on here and what I should do?
