I have this constant pressure in my head that is making my eyes pulse, it s hard to explain but it s like it s in rhythm with my heart beat, occasionally I have this pain in the left side of my chest under my breast that is like a really sharp pain for at least 5-10 seconds and then disappears, comes and goes intermittently with no warning, lately I ve also noticed that my right nostril drips clear fluid, like a tear drop, not often but I am concerned. If I stand to quickly or stretch I get light headed and blurry vision. HELP
