This weekend and Monday morning Addy had some fluid build up around the scar on her scalp, but none of the other usual symptoms for shunt problems (inconsolable, extra sleepy, lots of nausea, fever, bulging soft spot, neurologic problems, etc). When I asked the neurosurgeon's nurse what we should do about it, she said to go to the ER to get it checked out. It sounds all big and scary to say that you have to go to the ER, but it's the most expedient way to get some X-rays and a CT scan. So we had our first adventure at the local ER on Monday afternoon. They couldn't find where the fluid was coming from and it was mostly gone by the time the neurosurgeon's nurse finally called me back, so for now we're supposed to keep an eye on things (go back to the ER if she gets worse or there are more symptoms) and get an appointment to see the neurosurgeon in a couple of weeks for a follow-up.
Yesterday her shunt was almost completely back to normal. She was a little fussy (and insatiably hungry), but I think that may be teething (and normal). Today she's back to her old, happy, jabbery self and the shunt is back to normal again.
