Went To Derm. Said I Had Shingles. However I Have

Went to derm. Said i had shingles. However i have no blisters. But i have a rash on my back all around to my breast area. I had three big bumps in the middle of my breast and a little fluid came out. I am more itchy and bruised then pain. If it is shingles can it spread all over the body
