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.
Bonded leather refers to a polyurethane product that has leather shavings sprayed onto the back. The polyurethane component of bonded leather makes a durable sofa material, and it is one of the easiest leathers to care for. But bonded leather is not invulnerable to stains, wear or damage from harsh abrasives.
