Little bumps on the back of your hands can be caused by a wide variety of conditions, including keratosis pilaris, atopic dermatitis, and other skin problems. Most causes of bumps or rashes on the skin are harmless and can be treated easily.
Learn about the most common causes of bumps on the back of the hands.
5 common causes of bumps on the back of the hands
1. Keratosis pilaris
Also known as chicken skin, keratosis pilaris is a benign skin condition that causes tiny red, brown, or white painless bumps on the skin around hair follicles. These bumps are commonly seen on arms, thighs, cheeks, and buttocks but can be seen in any other part of the body where hair follicles are present.
The bumps contain excess keratin (a protein that helps form hair, nails, and the outer layer of skin) and are usually painless and not itchy
Keratosis pilaris cannot be cured or prevented but can be treated by using moisturizers, medicated creams, and laser therapy. Home remedies, such as the application of diluted apple cider vinegar or coconut oil, may also help reduce the appearance of keratosis pilaris.
2. Atopic dermatitis
Although scratching the little bumps may provide temporary relief, it can worsen the condition and even cause an infection. Medicated ointments, creams, proper skincare, and moisturizers may help relieve itching and prevent flare-ups.
Dyshidrosis is a skin condition where small, fluid-filled bumps appear on the hands, sides of the fingers, and sometimes on the feet. The little bumps cause severe itching and last about 3 weeks. Once the lesions are dried up, the skin on the affected areas appears dry.
There is a high risk of recurrence of the blisters, sometimes even before the complete healing of the previous blisters. In severe cases, the blisters merge together, forming a painful and itchy patch. These bumps are commonly seen in people in the age group of 20-40 years.
When the lesions are mild, medicated ointments, creams, and moisturizers will help with the symptoms. However, in severe cases, corticosteroid pills may be recommended by your doctor.
4. Ganglion cysts
Small ganglion cysts are pea-sized, whereas the larger ones are round and are about 2.5 cm. The cysts are filled with a jelly-like fluid. They may be painless or cause pain when they press on the nearby nerve and can sometimes interfere with joint movements.
