i am 53 * have a clear runny nose. I had this about 7 mos ago & with 3 bottles each of astelin & rhinocort aq. it went away. I have no headache, diziness, balance prob .jus this. I did have bronchitis in the middle of this episode.I quess this bout has lasted about 11/2-2mos. I went to an allergist & the drainage was checked for glucose on the strip. I read up to 74% of these can be false positive. The drainage is also in the back of my throat at times. no fever. I have empty sella & my prolactin level was nml. it did test positive for glucose. I have had no surgery or head injury. I have had allergies all my life, lived with a smoking parent. is there hope that this is not anything serios as csf? thanks the drainage tastes salty. It does drip more if I tilt my head forward at times & when I'm lying down at night.am curently on zpak as still have yellow mucus on cough? have had rocephin, avelox 5 days & levaquin750 5 days. am now taking shaklee supplements.
