I am wondering if the under eye swelling and sinus pressure are related and indeed if it could be something other than infection and if I CT scan will be of help to solving the issue of either or both. It sounds like your symptoms have been quite bothersome for some time and you should discuss them with your physician.
Cordovan is an equine leather made from the fibrous flat muscle (or shell) beneath the hide on the rump of the horse. The leather derives its name from the city of Cordoba, Spain, where it was originally prepared by the Moors.
Tuscany Leather is Semi-Aniline, which is dyed for color with a smaller amount of topcoat applied, which allows the leather to feel softer and show more natural grain, while still providing color uniformity and some protection against wear. Tehama Leather is Pure Aniline, which is dyed with no pigment or topcoat.
