I've noticed this used universally in Dutch and Belgian (Walloon & Flemish) programmes/youtubers videos, and more recently I've noticed it cropping up, still with other alternatives, in two German TV series Ella Schön and Bettys Diagnose.
Is this just a temporary fad, or are there some areas of Germany where this is part of the everyday vocabulary?
EDIT
My dictionary tells me this is Germanic word:
ORIGIN
Old English sārig ‘pained, distressed’, of West Germanic origin, from the base of the noun sore. The shortening of the root vowel has given the word an apparent connection with the unrelated sorrow.
