I have Idiopathic Intracranial Hypertension and I have two shunts. My LP shunt malfunctioned and I had two back to back revisions this year. The last one was in August. Since then, it has itched constantly and I now get a pocket of fluid at the incision site. It's about half the size of a dime and when I pop it, clear fluid comes out. Any idea what it could be? Is it worth bringing to my surgeons attention?
