What causes sudden burning and itching red rash on wrists that moves up the arms to ear canal clavicle face head with fever?
There are several potential causes for sudden burning and itching red rash on the wrists that spreads up the arms to the ear canal, clavicle, face, and head, accompanied by a fever. Here are some possible causes:
1. Allergic Reaction: An allergic reaction to certain foods, medications, or environmental triggers can cause a sudden red, itchy rash that rapidly spreads to different areas of the body, including the wrists, arms, and face. Fever may accompany severe allergic reactions (anaphylaxis).
2. Infections: Some infectious diseases can present with a rash and fever. Viral infections such as measles, rubella, and scarlet fever can cause a red, itchy rash along with other symptoms like fever, sore throat, and cough. Bacterial infections like cellulitis and erysipelas can also lead to a spreading, red, and painful rash.
3. Autoimmune Conditions: Certain autoimmune disorders, such as lupus and vasculitis, can cause inflammatory rashes that may start in one area and spread to other parts of the body. These conditions are often associated with fever and additional systemic symptoms.
4. Drug Reactions: Some medications, such as antibiotics (e.g., penicillin) or anti-inflammatory drugs (e.g., NSAIDs), can cause skin rashes as a side effect. These rashes can sometimes be accompanied by fever.
5. Insect Bites or Stings: Bites from insects like fleas, ticks, or spiders, or stings from bees or wasps can result in localized red, itchy rashes that may spread if the person is allergic to the venom or saliva. Fever can occur if the reaction is severe.
6. Sunburn: Prolonged exposure to sunlight can lead to sunburn, characterized by a red, painful, and itchy skin rash that can cover a significant area of the body. Fever is possible if the sunburn is severe.
7. Dermatological Conditions: Certain skin conditions, such as eczema (atopic dermatitis) or psoriasis, can flare up and cause red, itchy rashes that may spread over time. Occasionally, these flare-ups can be associated with fever.
It is important to consult a healthcare professional if you experience a sudden burning and itchy red rash that rapidly spreads to different parts of the body, especially if it is accompanied by fever. Proper diagnosis and treatment depend on identifying the underlying cause. The healthcare provider may perform a physical examination, ask about your symptoms and potential triggers, and may recommend tests such as blood tests or skin biopsies to pinpoint the exact cause of the rash.
