I have experienced the same symptoms as you but at an earlier age. I had a surgeon tell my mother and father that there were outlets of shunt revisions that can be done. I experienced great pain when I was younger from the fluid buildup. It took many times for revisions to get it right.

Because of the shunt being a foreign object in the body it may be the reason for what you are going through. My parents told me and my surgeon told them that that was THE reason for it. I had to endure great pain until they finally arrived at the right one where my body accepted it. They told my parents that was the logical way and only way for me to stop the pain I was having. I had my shunt(s) put in when I was born.

If you need to talk with me about this please do so.
