I was browsing through the Internet on my computer when I started to feel a headache coming on. I didn't think much of it because I've been getting headaches a lot over the past few weeks. But my headache got worse. I then felt a small lump under my left eyelid to the upper right. It feels like a very small ball, and it feels like I can move it around a little bit. I freaked out, of course, because "lumps" and "headaches" don't go so well together, health-wise. I tried to look at it in the mirror but I couldn't see it. I have no pain in my eye at all, or around the area. The only pain is my headache, which feels like it's radiating from above my left eye, where the lump is. ive done some research and I've seen a lot about chalazions, but my eye isn't red at all. It looks completely normal, except for the lump. And I haven't seen anything about the headache. Are the two related? Or could the headache be eye strain from the brightness of the computer?
