You are not being a baby! You should call your doctor right now! I do not have personal experience with a shunt, but I did have major spinal surgery so I know what I'm talking about when I say that your doctor is your most valuable resource! The people on this site are great, but your doctor is the only one who was there preforming the procedure. He (or she) is the one to ask any and all questions you have. It is 100% OK to ask "stupid" questions. Don't hold off asking an important question just because you're afraid it will be perceived as wimpy or dumb. I promise you no one at your doctor's office will think less of you for calling and asking. Remember, it is you who is ultimately responsible for your health.
