Hi Jessica, sorry to hear about your husband's health problems, I know what you mean about the military...
Anyway, he might want to look into a treatment called Vax-d, which can help with herniated disks and fluid leakage. It's non-surgical and not painful, and it may be covered by his insurance, if it's through the govt.
Best of luck to both of you!
I'm afraid I won't be much help on the electromagnetic therapy. I don't know anything about it.
As for leaking spinal fluid... CSF is important, it's not optional. It shouldn't be leaking, ever. Since you've already had the MRI, there's no reason you can't consult with a non-military physician about this... one office visit to review the MRI and provide a second opinion won't be expensive.
