Possible causes of a red, burning, itchy, warm-to-the-touch rash that spreads from the neck, face, and arms include:

- Hives (urticaria): Raised, red, itchy welts that can appear on the neck, face, and arms, often caused by an allergic reaction.

- Infection (viral or bacterial): Infections like measles, scarlet fever, or cellulitis can cause red, itchy rashes that may start from the neck and spread to the face and arms.

- Shingles (herpes zoster): A viral infection that causes a painful rash and blisters, typically on one side of the body and may involve the face and neck.

- Drug reactions: Certain medications can cause skin reactions, including red, itchy rashes that may spread from the neck to other areas of the body.

- Sunburn: Overexposure to sunlight can lead to sunburn, causing red, itchy, burning skin.

It is important to consult with a healthcare professional for proper diagnosis and treatment, as some rashes can be contagious or require specific medications to control symptoms and prevent complications. The healthcare professional will examine your rash, consider your medical history, and may recommend tests such as skin scrapings or blood tests to determine the exact cause of the rash and provide appropriate treatment.
