Tiny water bubbles after being outside.

[RyJae]

Okay I helped out with two questions to the best of my limited abilities so I have one in return. WHat causes tiny water? bubbles after working outside usually on hot/sunny days but sometimes just on warmer days.
They usually form on my shoulders and arm. I know medical advice and all that but this is not medical advice as they cause no damage they pop when rubbed and go away on there own. Just a total curiousity question, what are they?

I was going to say sweat, but I think what you mean is water blisters, in which case I would assume it's some sort of a heat rash, but of course IANAD.

You may be right, but I image googled and could find nothing that looks like what I have, sadly I just showered (Which the scrubbing pops them) or I would take pictures to show.
I will try to be more precise, and maybe your answer would still apply. These are spread out, no clusters, no color, about a a pencil tip sized. Maybe a total of 20 all over a day. Both on top the arms and under the arms though not in the armpit section.
They leave no marks whatsoever on the skin after popping, and thats about all I can think of.

Many thanks for your answer!
