Me too pal about 12 years ago, itching everywhere from the arms to the bell end, legs, feet and head. The Doctor said it’s unlikely to be diabetes but that’s what it turned out to be, apparently not that common apart from the genital area. Mine didn’t go fully until a good while after being diagnosed type 2, it seemed to burn itself out.Itching, especially around the privates, could be one of the signs of diabetes. I have Type 2 and that was one of the symptoms the doctors mentioned to me.
Hope it's nothing series, but you should "man-up" and get down the quacks (or apply to go on embarrassing bodies :)
The liver needs testing as well as itching is a sign of liver disease. I had the full suite of blood tests and a liver scan to rule out other factors.
