Peeling and Itching at Finger Joints: Causes and Solutions - Dermatology

More Info

---

Peeling and itching at the finger joints can be a concerning symptom, especially when it spreads from one finger to multiple fingers. Given your mother's age and the symptoms described, there are several potential causes that could be contributing to her condition.
1. Contact Dermatitis: This is a common cause of skin irritation and can occur due to exposure to allergens or irritants. If your mother has recently changed soaps, detergents, or even the type of gloves she wears while cleaning or cooking, this could lead to contact dermatitis. Symptoms typically include redness, itching, and peeling skin.

2. Eczema (Atopic Dermatitis): Eczema is a chronic skin condition that can cause dry, itchy, and peeling skin. It often flares up due to environmental factors, stress, or allergens. If your mother has a history of allergies or asthma, she may be more prone to developing eczema.

3. Psoriasis: This is an autoimmune condition that can cause red, scaly patches on the skin, including the joints of the fingers. Psoriasis can sometimes present with itching and peeling, and it may be associated with joint pain, which could indicate psoriatic arthritis.

4. Fungal Infections: Fungal infections, such as tinea (ringworm), can also cause peeling and itching. These infections can spread from one area to another, especially if the skin is moist or if there is frequent handwashing.

5. Nutritional Deficiencies: Deficiencies in certain vitamins and minerals, such as Vitamin B, Vitamin D, or zinc, can lead to skin issues, including peeling and itching. A balanced diet is essential for maintaining healthy skin.

6. Systemic Conditions: Certain systemic conditions, such as thyroid disorders or autoimmune diseases, can manifest with skin symptoms. If your mother has other symptoms, such as fatigue, weight changes, or joint pain, it may be worth discussing these with her healthcare provider.

Given that the condition has spread and has not improved with the use of Vaseline, it is advisable for your mother to see a dermatologist or her primary care physician for a thorough evaluation. A healthcare professional can perform a physical examination, take a detailed history, and possibly conduct tests (such as skin scrapings, patch testing, or blood tests) to determine the underlying cause of the peeling and itching.

In the meantime, here are some general recommendations that may help alleviate her symptoms:
- Moisturizing: While Vaseline is a good occlusive agent, it may not be sufficient for all skin types. Consider using a thicker cream or ointment specifically designed for dry skin, applied frequently throughout the day.


- Avoid Irritants: Identify and avoid any potential irritants, including harsh soaps, detergents, or chemicals. Wearing gloves while cleaning or doing dishes can help protect the skin.

- Gentle Cleansing: Use mild, fragrance-free cleansers to wash the hands, and avoid hot water, which can further dry out the skin.

- Hydration: Ensure adequate hydration by drinking plenty of water, as well as incorporating foods rich in omega-3 fatty acids, which can help improve skin health.

- Over-the-Counter Treatments: If itching is severe, over-the-counter hydrocortisone cream may provide temporary relief, but it should not be used for extended periods without consulting a doctor.

In conclusion, while there are several potential causes for your mother's symptoms, a professional evaluation is essential for an accurate diagnosis and appropriate treatment plan. Early intervention can help manage symptoms effectively and prevent further spread or complications.
