If the incision has a lot of tension (is very tight), some surgeons will leave the sutures in longer. However, 12 days for suture removal may be a little long and runs the risk of leaving suture marks or railroad track scars. You should call your surgeon's office to have your concerns addressed.
Italian seasoning is a spice mixture popular in many parts of the world that attempts to capture some of the most common flavors of Italian cooking. It is typically sold as a dried herb mix. It can contain a wide range of ingredients, but rosemary, oregano, thyme, and marjoram are usually some of the most common.
Great recipe for a really great Italian seasoning. Have you thought of adding a teaspoon of a savory blend. Winter and summer savory plants have different taste, one pine the other peppery. That's why a blend is best. I think that you are a bit skimpy in the red pepper flakes and them being optional, well that's silly.
