Don't bedbug bites tend to show up in lines?
Bedbug bites. Final answer. Not even going for a lifeline :)

The arm looks exactly like my legs when I was bitten by bed bugs in a hotel back in Kansas. My answer: bedbug bites.

The patterning (linear strips) seems to be a clue. I will go with Guttate psoriasis with koebnerization.
