What could be wrong?

[animaf]

I have had issues with headache, ear pressure (extremely painful at times), ringing, hearing going in and out, extreme dizziness for the last year. I have had normal reports from MRI, CT, MRA/V, LP, allergist, ENT, basic labs. Spent thousands of dollars. My CSF opening pressure was 7. From the reports I could find online, this seems low. Is it? I believe it's possible that I have a leak. After seeing many doctors, I was diagnosed with migraines and allergies. I am taking propranolol for the migraines, claritin D, flonase, and singulair for the allergies. This seemed to help , over the last three months I have resumed my life and typical activity level. The only med I feel that I can't live without (noticible difference if I don't take it) is the Claritin D...I've tried regular claritin and really need the decongestant. However, lately I have been experiencing return of dizziness, pressure, pain, hearing in and out, ringing...and I've been taking my meds regularly...any thoughts as to what is actually going on?
