Sinus problems:always running nose no cold,headaches

Hey I have a constant running nose. It has been going on for months now. I have taken allegy pills and sinus pills but they don't work. For the last few days I have had headaches on and off. I thought I had a some sinus build up in my forehead area and I have used a sinus rise several times. The sinus rinse just seems to have cleaned the inside of the nose it didn't work to stop the dripping or the headaches. I have been getting a few nose bleeds after I have used the sinus rise too. The sinus rise is called NeilMed Neti Pot.

Any thoughts about how to stop the headaches and running nose? Please and thanks.
