How Can Sphenoid Pressure With Pain Be Treated?

Hi, earlier today I stood up to get some food and I felt pressure by my left sphenoid behind my eye brow. My natural reaction/reflex to this was to squint my eye shut vigorously. After a while the pressure subsided and only reappeared for a short while after I squinted my eye shut again. The pressure was as close to zero as it could be, as long as I didn't squint my eye too much. Then it became consistent and squinting did no effect (still doesn't). Although before the pain was at the sphenoid, now it is more prominent in the eye socket. Now it comes in waves. The pain isn't great, mainly I'm just curios what it could be.
