A venous ulcer is superficial and painful. It is found on the lower leg or ankles. An arterial ulcer is usually on the foot but may be on the lower leg. It has a "punched out" look. The skin around it is very cool to the touch and often pale or shiny.
The arterial and venous systems are connected in the body tissues by capillaries, and also in the heart.

Answer An arterial ulser is an ulser on an artery. Nothing to play with for sure. -The above answer is not entirely correct. An arterial ulcer refers to an ulcer that may have developed from but is prohibited from healing by arterial insufficiency. These ulcers tend to be at the distal (farthest away from the body) part of the feet. These contrast to Venous ulcers (due to lack of the bodies ability to return fluid away from the legs), neurotrophic (diabetic) and pressure ulcers (decubitus ulcers).
The primary differences between venous blood and arterial blood are that arterial blood is oxygenated, under great pressure, and is moving from the heart, and that venous blood is deoxygenated, under low pressure, and is moving towards the heart.

Gangerene Arterial ulcer Venous ulcer Is this person diabetic? No, he is not a diabetic, but had ricketts as a child and now has poor ciruclation and a little swelling in his lower legs. Ricketts is caused by Vitamin D deficiency amongst other malnutrition. Poor circulation can be poor arterial blood flow or venous return both of which cause ulcers on the feet. Vitamin D, I have heard, can help with arterial ulcers. Perhaps your person doesn't absorb or metabolise Vit D very well. I'd see a Dr as these blisters, especially if they become sores, need to be cared for. Perhaps some compression bandages to prevent the swelling? Do some research on Arterial Ulcers versus Venous Ulcers so you know which you are dealing with. Good luck.
