Introduction
Itchy fingers with small bumps in summer, which get itchier when scratched, may be caused by physiological factors or pathological conditions such as dyshidrotic eczema or general eczema. Symptoms can be relieved through general treatments or medication. Besides these causes, conditions like scabies, tinea manuum (fungal infection of the hands), or contact dermatitis could also be responsible. It is important to seek timely medical evaluation at a hospital to determine the underlying cause and receive appropriate treatment.
Itchy fingers with small bumps in summer that worsen with scratching may be caused by physiological factors, or may be related to pathological conditions such as dyshidrotic eczema or general eczema. Symptoms can be relieved through general management or medication. Specific analyses are as follows:
1. Physiological Factors
If excessive spicy or irritating foods—such as ginger and garlic—are consumed during summer, skin metabolism may be affected, leading to red bumps and itching on the fingers. This is usually a normal phenomenon that does not require special treatment; maintaining a light diet is recommended.
2. Pathological Factors
1) Dyshidrotic Eczema
If fingers are not properly cleaned and cared for, prolonged exposure to sweat irritation may lead to dyshidrotic eczema, characterized by small blisters accompanied by intense itching. Patients may use medications such as miconazole nitrate cream, urea ointment, or compound clotrimazole cream under medical guidance.
2) Eczema
Eczema is a commonly seen clinical condition. When it occurs, small itchy bumps appear on the fingers, often with oozing, and typically distributed symmetrically. Patients may use medications such as mometasone furoate cream, pimecrolimus cream, or desonide cream as directed by a physician.
Besides the above causes, symptoms could also result from scabies, tinea manuum (hand fungus), or contact dermatitis. It is important to promptly visit a hospital to determine the exact cause and receive appropriate treatment.
