Shingles and muscle twitching all over body?

i have a burning itchy feeling on a patch of one side of my back, i thought this was the start of shingles outbreak, i noticed this 3/4 days ago and still there is no sign of a rash. More recently i started having other neurological symptoms like nerve pain behind my ear in the opposite side of my body, stomach muscle twitching, minor finger and lip twitching. im wondering what this means about whether i have shingles or not
