Thanks for your query.
It is most likely an allergy to some particles present, or due to heat (called thermal stimuli) at your working environment, as there are on apparent insect bites
. A course of anti-histaminics( such as, cetirizine
) will help.
Consult your doctor, who will order for allergy tests
, and apprise you of the entire range of particles to which you are allergic to.
