What are the warning signs of shingles recurrence?

The main precursors of shingles recurrence include: 1. Systemic symptoms: Patients may experience flu-like symptoms such as low-grade fever, body weakness, and loss of appetite. These symptoms occur due to the virus becoming active again within the body, affecting the body's temperature regulation center and energy metabolism. 2. Sensory abnormalities: Before recurrence, patients often feel pain, itching, numbness, or needle-like sensations on the skin localized to the area adjacent to the previously affected region by shingles. 3. Skin symptoms: The skin may develop a burning sensation, similar to the feeling of ants crawling, and red spots or blisters may appear, signaling another outbreak of shingles.
