Bumblebees and stinging nettle puzzle

Nettles and bees

Common Carder bumblebees are still busy collecting pollen from Hebe bushes 

and white deadnettles. 



In the late September wind, I watched common carder bees struggling to reach the flowers. which were surrounded by stinging nettles as they often are.
  One worker carder bee that was blown off-course onto a nettle leaf and buzzed in a way that sounded angry.

Can bumblebees feel nettle stings?

It seems unlikely that the bee was stung through its cuticle. 

 But could it have activated the nettle sting and then, via its antennae, would it have tasted the irritating contents of formic acid, histamine and acetal choline released by the nettle?

Or was it simply upset by the wind?
