Hi, Thanks for posting in HCM. I understand your concern. Shingles is caused by virus varicella zoster . It is also called herpes zoster. Shingles occurs when the virus that causes chickenpox starts up again in your body. The virus usually affects one nerve only and on one side of the body. Symptoms occur in the area of skin that the nerve supplies. The usual symptoms are itching, tingling, pain and rash. The rash could turn into clusters of blisters. Preceding to the appearance of these symptoms, you may have a headache and also feel like flu like having symptoms. Kindly consult Dermatologist for clinical evaluation and management. Hope the information provided would be helpful. All the best.
