Eczema, diabetic blisters and granuloma annulare are all possible causes of your symptoms.
Eczema is a term for several different types of skin swelling. Eczema is also called dermatitis. Most types cause dry, itchy skin and rashes on the face, inside the elbows and behind the knees, and on the hands and feet. Scratching the skin can cause it to turn red, and to swell and itch even more.
Eczema is not contagious. The cause is not known. It is likely caused by both genetic and environmental factors. Eczema may get better or worse over time, but it is often a long-lasting disease. People who have it may also develop hay fever and asthma.
The most common type of eczema is atopic dermatitis. It is most common in babies and children but adults can have it too. As children who have atopic dermatitis grow older, this problem may get better or go away. But sometimes the skin may stay dry and get irritated easily.
Treatments may include medicines, skin creams, light therapy, and good skin care.
2. Diabetic blisters
Diabetic blisters are relatively rare but reports on how often they develop vary. Blisters typically occur in people who do not control blood sugar well. They are painless and tend to heal on their own without treatment.
Diabetic blisters most often develop in people who do not control their diabetes correctly for several years. Despite this, some people may find that blisters are the first symptom they experience as a result of diabetes or even prediabetes.
Blisters are usually clear bumps that typically appear on the legs, feet, and toes, as well as the arms, hands, and fingers.
diabetic blisters often heal without treatment in 2 to 5 weeks. Treating diabetic blisters, therefore, usually focuses on preventing infection. One of the primary ways to prevent infection is to avoid puncturing or bursting the blisters.
In addition to reducing the risk of infection, it is also advisable to see a doctor or dermatologist to rule out more serious skin conditions that can develop in people with diabetes.
3. Granuloma annulare
Granuloma annulare is a skin condition that causes raised reddish or skin-colored bumps (lesions) in a ring pattern. The bumps are usually on the hands and feet.
Minor skin injuries and some drugs might trigger the condition. Different types affect adults and children.
The lesions usually disappear on their own within two years without treatment. But if you're bothered by how your skin looks or feels, your doctor can prescribe medications that can speed the disappearance of the condition.
