I too am experiencing problems with LP shunt failure. It has taken 6 months for the doctors to test it and finally believe me that it has failed. I am thinking of maybe getting a programable shunt so I do not have to go through 6 months of pain, memory problems and the meds are making my job impossible. Did you get another LP shunt? Or have you gotten the brain one? Do you feel any better? Is life normal? Please write me back, your pseudo sister.
