Re: Back Surgery
It is one of the possible side effects/complications they usually warn about prior to spine surgery, spinal taps, injections, etc. Anytime the spinal cord sheath is invaded, CSF leaks can and do occur. Sometimes this causes headaches, loss of hearing, etc. Normally these symptoms are temporary, lasting for less than two weeks, and aren't as severe while lying down, but there are instances of longer and worse symptoms.
