What are this random tiny blisters that have just appeared all

[coffeecoffeee]

Any idea what this is!? I went to the gym and then these tiny little blisters appear on my legs/arms back and stomach ?!

Not painful just made skin a really weird texture! A little bit itchy??

Sunburn?

Has that skin touched the benches and equipment ?

It's prickly heat

Majority of the parts with the blisters were under my clothes!

I was in the sun last week but have been moisturising and no peeling or anything.

They just started appearing over me on my drive home from the gym!!

Prickly heat/sweat rash. Take a cool shower and try not to scratch OP! Some antihistamine might help the itch.

It's nothing to worry about. Try wearing looser breathable clothes.
