Fingers have large itchy bumps

Swelling and itching on the fingers may be caused by frostbite, hand eczema, insect bite reactions, or other reasons. Appropriate medication should be selected based on the specific condition. Detailed analysis is as follows:

1. Frostbite

Frostbite is tissue damage caused by exposure to cold temperatures and commonly affects fingers, toes, ears, and the nose. After frostbite, the skin typically shows obvious congestion, swelling, and sometimes blisters. Treatment may include medications such as Yunnan Baiyao Tincture or Xiaozhong Zhitong Ding, used according to medical advice.

2. Hand Eczema

This is usually a skin inflammatory reaction triggered by contact with detergents, laundry powder, soap, or similar substances. During the acute phase, red patches appear, often accompanied by papules, vesicles, or bullae on the affected areas. Medications such as levocetirizine hydrochloride tablets or epiastin hydrochloride capsules may be taken under medical guidance.

3. Insect Bite Reaction

This occurs when fingers are bitten by insects such as mosquitoes or fleas, causing an inflammatory response. It leads to abnormal fluid leakage in tissues, forming raised, firm bumps at the site, along with symptoms of itching and pain. Treatments may include fluticasone propionate cream or compound camphor cream, applied as directed by a physician.

Besides the common causes listed above, other possible conditions include papular urticaria, tinea manuum (hand fungus), or dyshidrotic eczema. If discomfort symptoms occur, it is recommended to seek timely medical attention for proper diagnosis and treatment.
