Signs and Symptoms of Shingles
Shingles, also known as herpes zoster, is characterized by the development of small, fluid-filled blisters on one side of the body or face. Although the rash can appear anywhere, it commonly starts around the waist. Prior to the eruption of the rash, individuals may experience increased skin sensitivity and sensations such as tingling, itching, or burning.
Early symptoms of shingles may also include fever, headache, upset stomach, sensitivity to light, as well as fatigue and lethargy. The virus responsible for shingles travels along nerves, leading to mild to severe sharp, stabbing, or radiating pain. Typically, the blisters scab over within a span of 7 to 10 days and completely heal within 2 to 4 weeks.
Long-Term Complications of Shingles
While antiviral medications are commonly prescribed by medical professionals to treat shingles, their use does not always guarantee the prevention of complications. Although rare, shingles rashes located on the face can potentially lead to blindness or deafness on the affected side. Moreover, in severe cases, shingles can cause damage to the nerves in the affected area, resulting in a condition known as postherpetic neuralgia (PHN). Individuals suffering from PHN may experience persistent pain for months or even years after the rash has healed.
