My father is 80 years old and has long-standing
diabetes. For the past one month, he has been suffering from a skin problem that started as small fluid-filled bubbles (blisters) on his hand. Over time, these blisters increased in number and gradually spread to other parts of his body, including the arms and legs.
Many of the blisters become large, filled with clear fluid, and then burst on their own, leaving open wounds. Some areas have developed dark scabs, raw skin, and sores that are slow to heal. The surrounding skin often looks red, dry, and irritated. Because of his age and diabetes, we are worried about infection and delayed healing.
This condition seems to be worsening despite basic care, and it is causing him discomfort. We would like to know:
What could be the possible cause of these recurring blisters and wounds?
Is this related to diabetes or an infection/allergic or autoimmune condition?
What immediate steps can we take to get relief and prevent further spreading?
