What is the reason for the red and hard bumps on the body ?

I got big, red pimples on my body, which were hard and itchy. It could be papular urticaria.

Papular urticaria is also called insect bite dermatitis. It refers to an inflammatory skin disease caused by insect bites on human skin.

Papular urticaria is often associated with arthropod bites, such as mite bites.

Papular urticaria usually occurs in the summer and often occurs on exposed parts of the body.

When the body is bitten by an insect, there will be a stinging sensation, burning pain, and unbearable itching. Local redness, swelling, wheals or ecchymosis, and papules may appear. Blisters and bullae may appear on the surface, and bite marks may sometimes be seen in the center of the lesions.

After papular urticaria occurs, you can apply externally drugs such as Pi Yan Ping and Wuji ointment to treat insect bite dermatitis. At the same time, oral cyproheptadine, vitamin C, dexamethasone and other drugs can be used for systemic treatment.

In severe cases, intravenous infusion treatment is required. Anti-allergic drugs such as calcium gluconate, dexamethasone, vitamin C, etc. can be used for intravenous infusion.

To prevent the occurrence of insect bite dermatitis, first of all, you should pay attention to cleanliness and hygiene, eliminate pests in the surrounding environment, wash and expose clothes and quilts frequently, and avoid eating foods that can cause allergies in daily life. Eat more foods rich in vitamin C.

1. General treatment

Because the causes of urticaria vary, the treatment effects are also different. The specific treatment measures are as follows:

(1) Eliminate the cause. Every patient should strive to find the cause of the attack and avoid it. If the cause is infection, the infected lesions should be treated actively. If the allergy is caused by drugs, the allergy medication should be stopped; if the allergy is caused by food, find out the allergic food and stop eating this food.

(2) Avoid triggering factors. For example, for cold urticaria, you should keep warm; for acetylcholine urticaria, you should reduce exercise, sweating and mood swings; for contact urticaria, you should reduce the chance of contact.

Immunosuppressants

When patients with chronic urticaria have an autoimmune basis, the disease recurs, and the above treatments cannot achieve satisfactory results, immunosuppressants can be used. Cyclosporine has a good therapeutic effect. Azathioprine, cyclophosphamide, methotrexate and immunoglobulin can all be tried. Tripterygium wilfordii also has a certain therapeutic effect. Due to the high incidence of side effects of immunosuppressants, they are generally not recommended for the treatment of urticaria.

In addition, drugs that reduce vascular permeability, such as vitamin C, vitamin P, calcium supplements, etc., are often used in combination with antihistamines. If it is caused by infectious factors, appropriate antibiotics can be used for treatment.
