last night i woke up several times with really itchy hands, i am surprised i didn't split the skin open with my fingernails they were that itchy... it seemed they were a bit puffy and red and at one point they were so bad i had to get cold wet facewashers to wrap them in because i couldn't stand it... when i woke up they were back to normal, theres no bites or lumps or any sign of anything any ideas?
