What you describe suggests that you may have chronic inflammation of your nose and sinuses.  The simplest test is direct examination of the inner lining of the nose by a doctor looking up into your nose with an instrument.  The sinuses cannot easily be examined this way but require CT exam of the sinuses by a type of x-ray machine.

Routine use of a nasal steroid spray can be very effective in decreasing inflammation in the nose and sinuses along with mucus production.  When a nasal steroid spray is used regularly it can prevent inflammation.  However it does not provide immediate relief of symptoms.  It may need to be used every day for several weeks to months to notice improvement in the symptoms.  To get the most help from any nasal spray first do a nasal wash to remove mucus from the nose and sinuses.  To learn more about this technique please read our nasal wash treatment information by copying and pasting this address

As for the headaches while studying, watching TV or working on your PC, you might want to have your eyes examined or try to see if you may be accidently holding your head and neck at an odd angle and that that could be causing the headache.
