Rashes on the neck and arms can result from various causes, including allergic reactions to products like lotions or detergents, skin conditions such as eczema or psoriasis, or infections. Environmental factors, such as heat or humidity, can also trigger rashes. If the rash is persistent, severe, or accompanied by other symptoms, it's best to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
