Also i expect it's cold as hell where you live right now, i lived at an apartment that did not have central air connected to a humidifier like most houses do, and the combination of winter dryness and the my gas heated apartment really dried me up and even causes a crack in my guitar! But if you get better during summer i would think winter and gas heated homes could be a culprit, but again i'm no doctor, go find a dermatologist if you haven't already.
p.s
You look Swedish as Fuck!
