My SIL is an RN and last year i got her a massage chair and this year i got her massage booties and I hit up sales today and got her a neck massager thingy for next year (I hit after Christmas sales for the following Christmas gifts because I'm a tightwad)
I'm figuring after next year I'm out of stuff to vibrate her to death with...
Good thought on the shower massager though. .. might look for some sales.. deep thoughts!
A foot Jacuzzi with massage things on the bottom. Great after working on your feet for 12 hours.
