Suggest Treatment For Recurrent Shingles Infection

I have shingles for the second time . The lesions are across the left side of my face , spreading from nose,cheek,chin and neck. The first time I had them it was under my right breast, spreading across to right hip area . This happened 5 weeks after back surgery . As the area started to heal, I developed a large abscess and infection . I was admitted to the hospital and had surgery immediately to remove abscess and drain the area of infection . The culture revealed positive MRSA. Then treated with a combination of IV, antibiotics for about a week . Can you tell me what the protocol is to treat and prevent infection ?
