5. Unexplained Fever
   Recurrent low-grade fever (100°F-102°F) is another common early sign of lupus. These fevers are often unexplained, meaning they occur without an apparent cause, such as infection. The fever may come and go, lasting for days or even weeks. While a mild fever may seem insignificant when accompanied by other symptoms, it can be an early indicator of an autoimmune disease such as lupus.

What to watch for:
Frequent fever without signs of infection (e.g., cough, sore throat).
Low-grade fever that lasts for days or weeks.
Feeling feverish but without accompanying symptoms.

6. Hair Loss (Hair loss)
   Hair loss, or alopecia, is a common symptom of lupus and can occur suddenly or gradually. The hair may thin over time, or in some cases, it may fall out in patches. Hair loss is usually caused by inflammation of the skin and scalp. In addition to thinning hair, some people with lupus develop sores or lesions on the scalp, which can also contribute to hair loss.

What to watch for:
Noticeable thinning of hair or bald spots.
Brittle or brittle hair that breaks easily.
Skin lesions or sores on the scalp.

7. Mouth or Nose Sores
   Painless sores in the mouth or nose are another early sign of lupus. These sores can occur on the roof of the mouth, inside the cheeks, gums, or lips. Unlike cold sores, lupus-related ulcers usually do not cause discomfort but can persist for weeks or months. Some individuals also develop ulcers or sores inside the nose, which can be tender or painful.

What to watch for:
Painless sores inside the mouth or lips.
Frequent nose sores that do not heal easily.
Nasal bleeding associated with nasal ulcers.
