The symptoms of herpes zoster primarily manifest as irregular erythema on certain parts of the body's skin, followed by clusters of rice-grain or mung bean-sized raised vesicular rash, blisters, and blood blisters. These rashes generally appear on one side of the body, not crossing the body's midline, and are accompanied by local sensations of burning, scalding pain, stabbing pain, numbness, itching, and other abnormal neural sensations.
