Possible Causes
Pressure ulcers are sores that occur when pressure cuts off the
blood supply to the skin, or when any type of interuption occurs
to the skin (like a crack, a red "hot" spot, etc).
Force or friction against the bottom of your foot causes the
skin to thicken, forming a callus. If
the skin keeps thickening, the callus presses up into the foot.
This kills healthy tissue and causes pain. Unfortunately, you
may not notice the pain if you have neuropathy,
a health problem that limits how much feeling you have in your
feet. As healthy skin dies, an ulcer fornis. Ulcers may progress
from hot spots to infected wounds very quickly.
Left untreated, an ulcer may allow infection to enter your body.
If infection reaches the blood stream or bone, your life or limb
may be at risk. But with your doctor's help,
your health can be protected. Pressure ulcers can be controlled
and even prevented with the help of a podiatric
physician.

Treament
To assist healing, thickened skin around the ulcer may be cleaned
away. Medicated ointment or cream may be applied to prevent infection.
Sometimes a special dressing is used to help keep the wound dry.
Reducing force to take pressure off hot spots and ulcers, your
doctor may prescribe orthoses.
These custom- made shoe inserts absorb or divert pressure from
problem areas. Special shoes or temporary
casts may also be used.
Using antibiotics to control or prevent infection, your doctor
may prescribe antibiotics. Take them all, and take them as directed.
If you stop using an antibiotic too soon, the infection may come
back.
If surgery is needed surgery may be needed if infection enters
deep tissues or bone. In such cases, your
doctor cleans away the infection while removing as little tissue
or bone as possible. You may also be given intravenous (IV) antibiotics
to fight the infection.
