As your husband is a diabetic and moreover there is a soft sore on the
foot,so the possibility of diabetic
foot is there. Diabetic
foot is an umbrella term for
foot problems in patients with diabetes mellitus.
To prevent diabetic foot ulcers,he should have good foot hygiene, wear diabetic socks and shoes, and avoid injury.A consultation of a podiatrist will be the best.
Take care and pls do keep me posted on how your husband is doing or if you have any additional doubts.
