Do i go to work just told i have shingles?

Yes: There is no risk of spreading it. Often the pain can limit activity, but if you feel up to working then by all means go.

You may: Shingles is a disease that you should take "contact precautions", if it affects a part of your body that will not come into contact with anyone (as your chest or back), you may go to work. I suggest that you wear 2 layers of clothing so no one will contact the lesions. If you work with young children, or elderly people, then i would wait for the lesions crust over before returning to work.
