What causes peeling of finger joints?

The finger joints are very flexible and can help people complete a series of complex movements. They are an indispensable function for people to use tools and adapt to the environment. However, finger joints are also prone to problems. For example, peeling of the finger joints is a relatively common skin disease, which has a certain impact on the mobility of the joints. So, what is the cause of peeling of the finger joints?

1. Ringworm

A common cause of peeling of the hands is tinea manuum caused by fungal infection, which is often limited to one side. Peeling occurs first on one hand and then spreads to both hands. The palms appear erythematous, inflamed, and itchy, and most patients with tinea manuum also suffer from tinea pedis. The hyperkeratotic type is mainly characterized by excessive skin keratinization, roughness and lack of sweat, and cracking of the skin in the cold winter.

Various antifungal topical drugs are suitable for treatment, and oral antifungal drugs can be used in severe cases. Because tinea manuum is contagious, you need to go to the hospital for early diagnosis and treatment, and insist on applying the special ointment prescribed by the doctor.

2. Peeling

The white skin on both hands peels off, but there is no itching or inflammation. Doctors point out that this is the most common and most likely symptom of hand keratin exfoliation in early autumn. Although it affects appearance, it generally does not require treatment. It will heal on its own after 2-3 weeks as long as you avoid contact with irritating chemicals such as soap and hand sanitizer.

It can be combined with oral medication for treatment: soak 30 grams each of the Chinese medicine Atractylodes lancea, Phellodendron chinense, and Atractylodes lancea, apply them on the palms, and take vitamin C at the same time.

3. Keratolysis

This is a superficial exfoliative skin disease of the stratum corneum of the palms and soles. The cause is unknown. The skin lesions are initially white spots the size of millet, which gradually expand to the surrounding areas, similar to blister membranes with dried blister fluid. They can easily rupture naturally or be torn into thin paper-like scales. There are no obvious inflammatory changes and no itching. Low-concentration keratin peels or mild lubricants can be used for treatment.
