Why Do My Legs Itch? What Should I Do?
Some patients often experience itching in their legs, which can be caused by various factors. One common cause is skin diseases such as eczema or atopic dermatitis, which can manifest as symmetrical red patches, peeling, and itching on the skin. Dry dermatitis can also lead to leg itching. It is important not to scratch the affected area to avoid scarring. In addition to these causes, there are many other factors that can contribute to leg itching. What are the causes of leg itching, and how can it be treated?
Firstly, it is important to consider whether dryness is the cause, especially in northern regions where the weather is dryer and frequent bathing can lead to itching in the legs. Treatment involves reducing the frequency of baths and applying moisturizing oil regularly, such as once a day. This helps to keep the skin hydrated and alleviate itching.
Secondly, allergies can also cause leg itching, manifesting as isolated itching without any rash. In such cases, oral antihistamines can be considered to suppress the allergic reaction and improve the itching. For leg itching accompanied by a rash, the cause should be identified based on the appearance of the rash, which can vary widely. It is recommended to consult a dermatologist for accurate diagnosis and treatment.
Contact dermatitis refers to an inflammatory reaction of the skin that occurs after contact with certain external substances. It commonly affects exposed areas of the body and can manifest as erythema, edema, papules, and other symptoms. In severe cases, there may be erosion, exudation, and even necrosis, often accompanied by itching. Although this condition is not contagious and does not pose a life-threatening risk, it can cause discomfort and adversely affect daily life when severe.
For home care, patients should maintain a positive attitude, establish confidence, and cooperate fully with their doctors to facilitate the relief and recovery of the condition. For infants and children with contact dermatitis, family members should avoid feeling annoyed or discriminatory due to their crying or fussiness, and instead provide them with more care and understanding. Medication should be used under the guidance of a specialist to prevent worsening of the condition. Additionally, using a soft towel to wet compress the affected area for 15-30 minutes can help soothe the skin and can be repeated several times a day.
