A pain at the top of the eyes is at the location of your frontal sinuses. A nasal spray will not reach that location because of gravity.
One of the possibilities, and I just say possibility (because sinus problems are still a medical frontier) is a fungal infection. This is a rather recent discovery by the Mayo Clinic (Google: mayo sinus fungus).
It won't necessarily cause a blockage, often a constant irritation and allergic reaction, which may or may not show up on a scan.
The principals of the Mayo study are still trying to find a way to get an anti-fungal spray that reaches into the upper sinuses, for which they have a method patent. Good luck to them, it would be a major breakthrough.
If you do, in fact, have a fungal infection, the only cures, at present time as far as I know, is surgery, which is not very effective, or the annoying, mildly risky Flip-Turn Sinus Flush which i mentioned earlier, which judging from the feedback i am receiving, is highly effective.
