I went out for a hike in the sun two weekends ago and when I came back I noticed the my middle finger knuckle was itchy. The skin is bumpy, rough and dry. Now my pointer finger knuckle is the same way. I'm 21, female, no medications, lactose intolerant but no allergies other than that and pets (cats dogs, rabbits, hamsters etc). I've never had itchy skin like this before
