I feel your pain brother. I was at Mayo last nov.,and diagnosed with CSD. Mine started 27 mos. ago. I too had numerous tests and scans by a variety of specialists before heading to Mayo. They believe it first started out with migraines over a period of years. Then in March of 2010, I came down with what my pcp thought was an ear infection. I struggled the next few wks with intermitant dizziness but was still able to work. Then came the boatloads of anxiety. It came in unpredictable waves so strong that I could not drive or be driven for several mos. For the next year and a half, I was put on 10 or 12 different meds. including anti-depressants and anti-seizure types. Not one helped and often made me feel worse. I too use a small daily regimin of anxiety med (benzodiazapine). This does not cure or eradicate the symptoms, but rather settles them a little. Aside from the personal and professional ramifications, the hardest thing is to get the local doc's to take an interest in understanding this illness and the possibility of emerging treatment. Sorry to be longwinded, I was just curious if your situation was the same. Would love to hear from you or anyone else similar experience's. Best of luck.
