I had a spontaneous CSF leak 9 years ago. I was one of the lucky ones that got diagnosed right away but they were unsure how to treat it. Long story short, Get the MRI to confirm diagnosis. Skip the cisternagram, a useless test in most cases, never did show where my leak was and was VERY painful! Bed rest didn't work either and resulted in horrible ringing in my ears. Go for the blood patch. I needed two of them but it did the trick. It took a good 6 months to really feel myself again but I am fine now and never had another reoccurance.
