Hi Kriserin,
Welcome, welcome. I have a 29 year history with shunts. When I had my last shunt, I frequently had discomfort which I can only discribe as an arthritic type of discomfort that radiated from my collar bone down my right arm. Often, sleep would allieviate this, sometimes it wouldn't. Since my most recent shunt revision in Dec. 1998, I no longer experience this. I also sometimes experienced a cramping type of sensation at the distal end of the tube in my abdomine.
