Neither in Slovakia nor anywhere in the world is there a spring, no cure for beret ulcer. A shin ulcer is a vascular disease in which the blood vessels die and the affected area is not supplied with blood. The place at the bottom of the calf is the dead tissue that is falling apart. It flows, it stinks, it literally rots. It's a terrible and fatal disease. (No medicine can handle this situation. It is necessary to get the affected limb to restore blood supply. Good, healing cover and elastic bandage, properly placed, from the knee to the toes. And of course anxious hygiene. I regret anyone who has a shin.
