Introduction
Itchy bumps with a central spot on the body may be caused by conditions such as papular urticaria, neurodermatitis, or prurigo nodularis, and treatment should be based on the specific underlying cause. Prurigo nodularis may be associated with gastrointestinal dysfunction and insect bites. In the early stage, it may present as rice grain-sized red papules, and can be treated with medications such as fluticasone propionate cream or Wumiao Shuixian ointment.
Itching with raised bumps on the skin that have a central dot may be caused by conditions such as papular urticaria, neurodermatitis, or prurigo nodularis. Treatment depends on the specific cause. Details are as follows:
1. Papular Urticaria
This is an allergic skin condition caused by insect bites. The characteristic lesion is itchy skin bumps. Under medical guidance, treatments may include calamine lotion or oral cyproheptadine hydrochloride tablets.
2. Neurodermatitis
Main contributing factors include excessive mental stress, endocrine disorders, and chronic local infections. Inflammatory stimulation may lead to redness and itching in the affected area. Topical medications such as mometasone furoate cream or triamcinolone acetonide/econazole cream can be applied under medical supervision.
3. Prurigo Nodularis
This condition may be associated with gastrointestinal dysfunction and insect bites. In the early stages, it may present as millet-sized red papules accompanied by itching. Treatments may include fluocinonide propionate cream or Wumiao Shuixian ointment, used according to medical advice.
In addition to the above causes, similar symptoms may also result from herpes simplex, herpes zoster, or tinea corporis. Avoid scratching with hands and maintain cleanliness of the affected area.
