Are diabetic foot ulcers painful?

Are diabetic foot ulcers painful? So are they painful? That depends on the cause. So more than half of patients with a diabetic foot ulcer have neuropathy, which is nerve damage to the foot, and because of nerve damage, most ulcers are not painful, because nerve damage prevents pain from being present. is a relatively small number of people who have diabetes and artery disease causing ulcer who do not have nerve damage and in those they can be painful but that's the the minority people maybe five to ten percent of people who just have artery disease but no nerve damage so they're usually painless.
