Shingles blisters are not usually random, they run along a nerve path. For example, they might run from the spine around the side to the tummy. Or from somewhere on the head to the eye area. They are painful, if I remember correctly, and they don't pop right away like the ones you describe.
If yours are random, in several locations, I'd say no to shingles. JMHO.
God is our refuge and strength,
an ever-present help in trouble.
Therefore we will not fear,
though the earth give way
and the mountains fall into the heart of the sea.
--Psalm 46:1-2
