Pain and a burning sensation may accompany the skin rash. Over time, the skin rash may turn to blisters that fill with body fluids. The itchiness can spread to nearby areas when the blisters break and discharge their fluid contents. Bursting of the blisters leads to a burning sensation on the affected skin area. If the pain and skin rash occur close to the eye, the patient should seek immediate medical attention to prevent eye damage.
Shingle infections usually cause skin sensitivity in the affected area. This sensitivity may arise before the skin rashes appear and may last long after the rashes heal. Skin sensitivity is highest at the point where blisters develop and can spread to the surrounding tissues when the blisters burst open. Sensitivity associated with shingles may feel like a sunburn to the patient.
