Condensation inside lens

hi ive never had this problem before. recently when ive been going out ive noticed the sigma 20mm 1.4 art lens is getting condensation on the inside of the lens behind the front element and right in the middle.

i managed to make it disappear while i was out by holding something warm (my sleeve) on the effected spot.

is this unusual and something to worry about? picture below

thank you
