Red Bumps on Hands: Causes and Solutions - Dermatology

More Info

---

The appearance of small red bumps on the skin, particularly on the hands and arms, can be concerning and may indicate a variety of underlying conditions. Based on your description, it seems that these bumps are transient, appearing after meals and disappearing after a couple of hours. This pattern, along with the associated itching, suggests a possible allergic reaction or a dermatological condition.

One potential cause for the red bumps could be urticaria, commonly known as hives. Urticaria is characterized by raised, itchy welts that can vary in size and shape. They often appear suddenly and can be triggered by various factors, including food allergies, medications, insect stings, or environmental factors. In your case, since the bumps appear after eating, it might be worth considering if you are experiencing a food allergy, even if you have been avoiding seafood. Other common allergens include nuts, dairy, eggs, and certain fruits.

Another possibility is contact dermatitis, which occurs when the skin reacts to a substance it has come into contact with. This could be due to soaps, detergents, or even certain fabrics. If you have recently changed any products you use on your skin or in your home, this could be a contributing factor.

Additionally, keratosis pilaris is a benign condition that causes small, red or skin-colored bumps, often on the arms, thighs, and cheeks. While this condition is not typically associated with itching or a sudden appearance after meals, it is worth mentioning as a common skin issue.

Given your history of having sensitive skin and a tendency to develop allergies, it is essential to keep a detailed diary of your symptoms. Note when the bumps appear, what you have eaten, and any other potential triggers, such as new products or environmental changes. This information can be invaluable for your healthcare provider in determining the cause of your symptoms.

For immediate relief, consider using over-the-counter antihistamines, which can help reduce itching and swelling associated with allergic reactions. Additionally, applying a cool compress to the affected areas may provide temporary relief from itching.

However, since your symptoms have been persistent and seem to be worsening, it is advisable to consult a dermatologist or an allergist. They can perform a thorough evaluation, which may include skin tests or blood tests, to identify any specific allergens or underlying conditions contributing to your symptoms. A healthcare professional can also recommend appropriate treatments, which may include topical corticosteroids for inflammation or other medications tailored to your specific diagnosis.

In summary, the red bumps on your hands could be due to several factors, including allergies, contact dermatitis, or other skin conditions. Keeping a symptom diary and consulting with a healthcare professional will be crucial in identifying the cause and finding an effective treatment plan. Your health and comfort are important, and addressing these symptoms early can help prevent further complications.
