Itchy bumps on the back of the hand, especially after scratching, can be caused by various factors, including dry skin, insect bites, contact dermatitis, eczema, and urticaria. Appropriate measures should be taken based on the specific cause.
Dry Skin
When skin lacks moisture, it can become dry and itchy, leading to small bumps after scratching. Keeping the skin hydrated is essential. Moisturizers like petroleum jelly, urea cream, and vitamin E lotion can help.
Insect Bites
Insect bites on the back of the hand can release toxins that cause itching and small bumps. Applying cooling oils, menthol rubs, or insect repellents like citronella can provide relief.
Contact Dermatitis
Contact with certain substances, such as detergents or chemicals, can cause an allergic reaction and inflammation on the back of the hand. Avoiding allergens and using topical treatments like calamine lotion, dexamethasone cream, or hydrocortisone cream can help manage symptoms.
Eczema
Eczema, caused by a combination of internal and external factors, presents with itching and papules. Avoiding scratching and taking oral antihistamines like loratadine, cetirizine, or ebastine can help alleviate symptoms.
Urticaria
Urticaria, often triggered by food or medication, causes wheals and itching on the skin. Antihistamine medications such as chlorpheniramine, levocetirizine, or olopatadine can be effective in managing the condition.
Conclusion
If symptoms persist or worsen, it is important to seek medical attention for accurate diagnosis and appropriate treatment. Proper care and timely intervention can help alleviate discomfort and prevent complications.
