2. Skin patches
The second characteristic symptom of Sweet syndrome is how dynamic the rashes behave. They don’t just appear and disappear, they follow a very specific pattern that can help determine at first glance that you have Sweet syndrome. First, the bumps appear on the upper half of your body, especially the arms, the neck, and the face, but it is also common to see them appear on your legs.
The chest, the abdomen, and the back are uncommon places where to find these skin rashes. Over the course of days and even weeks, the bumps can multiply and rashes grow so much that they merge together and become skin patches. These skin patches are also very tender and they can make your skin hurt. You are more likely to injure your skin, and it might bleed or become scarred. You need to keep an eye on your patches to prevent possible infections.
