Localized skin hardening occurs on the fingers and toes.
Localized skin stiffness on fingers and toes may result from physiological factors, or could be caused by pathological conditions such as Sjögren's syndrome or tenosynovitis, requiring appropriate medical treatment. The specific analysis is as follows:
I. Physiological Factors
In winter, inadequate warmth preservation can affect overall blood circulation. Poor circulation may lead to body chilling, causing numbness and stiffness in limbs, including localized skin stiffness in the hands or feet. This is a normal physiological phenomenon, and symptoms usually subside once proper warming measures are taken.
II. Pathological Factors
1. Sjögren's Syndrome
This is an autoimmune disease that causes elevated immunoglobulin levels in the blood, increasing blood viscosity, which may lead to stiff skin on the hands and feet. Treatment should follow medical advice and may include medications such as diclofenac sodium sustained-release tablets, celecoxib capsules, or meloxicam tablets.
2. Tenosynovitis
A common inflammatory condition of the tendon sheath, tenosynovitis involves inflammatory exudation into tissues surrounding the joints, leading to swelling and resulting in stiff skin on the hands or feet. Treatment should follow medical guidance and may include medications such as ibuprofen sustained-release capsules, naproxen sustained-release tablets, or lidocaine hydrochloride injection.
Besides the above-mentioned causes, skin stiffness may also result from factors such as ganglion cysts, scleroderma, or rheumatoid arthritis. It is important to promptly visit a hospital for examination to determine the exact cause and receive appropriate treatment.
