Thank you for the picture. That really helps. I can tell you with 110% confidence that the swelling you are experiencing is not from a blocked shunt.
From the picture you uploaded it looks like you have orbital fat prolapse. This is a benign condition and not a sign of anything serious.
The most common cause of dark circles under the eyes is breakdown of the orbital septum which allows the normal orbital fat tissue that surrounds and cushions your eyeball to "pooch" forward.
As you know, there are tons of creams and lotions for the ladies to use for this issue. Why are there so many different ones? Because none of them work :-)
With age the thin, tough membrane (orbital septum) that keeps the normal fat pad in place behind your eye becomes weak and tears. When this happens you start to notice the swelling, or bags, under your eyes. It is nothing to worry about.
The only way to treat this problem is with surgery, called a blepharoplasty
. Many times it can be done in a procedure room in the ophthalmologist
Here is a good webpage that discusses this surgery:
