having seen these pics that's not what i expected when you said bruising - i was thinking lots of small round bruises which i have seen tons of with a whole range of causes
do they feel like bruises in that they're sore? or itchy? the one on your inside arm looks kinda like some kind of contact rash in how the inside of your elbow is spared
make sure to be pushy for answers if you don't get answers and if the marks remain or get worse~
