1. Insect bites

After being bitten by insects, the skin may show redness, swelling, pain, itching, and lumps. It is recommended to keep the affected area clean, avoid scratching with hands, and prevent secondary infection. Under a doctor's guidance, medications such as herbal balm, floral water, or wind-relieving oil can be applied.

2. Urticaria

Urticaria is an allergic condition. Symptoms are often transient but may recur in some cases. Contributing factors include food, infections, medications, and skin contactants. Patients should avoid exposure to triggering substances and receive appropriate treatment for underlying conditions.

3. Eczema

Eczema presents in various forms—some people develop papules, others small bumps or tiny red rashes. It is advisable to maintain good indoor ventilation and avoid excessive room temperature. Additionally, under medical supervision, antihistamines such as cetirizine tablets, loratadine tablets, or chlorpheniramine tablets may be taken for treatment.

Besides the above, small red bumps on the body could also result from drug eruptions. Patients are advised to follow a light diet and avoid spicy or irritating foods.

Treatment may involve general management and medication. If a patient has been in a damp, enclosed environment for a prolonged period, it may affect the body and lead to the appearance of such red bumps.

Does lupus initially present as small red bumps?

In general, the initial manifestations of lupus erythematosus are varied and do not typically appear as small red bumps. If you experience any discomfort, seek medical attention promptly and receive symptomatic treatment under the guidance of a qualified physician. One of the early symptoms of lupus erythematosus is the malar rash, which is not an ordinary small red bump, but rather a symmetrical red rash that spans the bridge of the nose and both cheeks, with relatively well-defined borders resembling a butterfly.
