Weird stabbing head pain?

Yesterday I went to the doctor for some ongoing symptoms that nobody’s really figured out yet.

Anyway, I had my blood drawn, took a nap a few hours later, woke up and had this weird stabbing pain in my head? It’s on my left side, and feels like it’s behind my eye somewhere, but not really related to my eye. It’s just a second or two long, like a jolt, every few minutes. It’s happened all evening and now all day thus far. Does this sound concerning? I’ve never had a pain like it before. My blood was drawn on the left side and the tech was a little rough.

Blood pressure was normal at the doctors appointment, pulse was higher than my normal, oxygen 99%.
