My partner goes through the same thing he wont go to the doctor cause he says its nothing,but when hes scratching it looks like hes going to rip them off
,so i pry his hands away and have a look at his testies
and theres nothing no irritations no evidence of anything biting him NOTHING,i too am baffled
the scratching happens at least twice a day(thats a bad day) and sometimes hes not scratching for a couple of days(weird) i cant explain it nor do i feel i've helped you in anyway(but his last scratch was 4 days ago)
happy new year!
