It' always great to hear what other people are doing with the same experience and I'm so happy for people who have found solutions, however, in the last 10 years that I have been itching to the point of tears after each shower not one of the mentioned solutions have worked for me! I have resigned to the fact that this is something I have to live with for the rest of my life as expert doctor opinions and suggestions have also failed! 

My itchiness happens all over my body: back, legs, arms, tummy. I love having showers as there's nothing like the feeling of cleanliness but at the same time I hate it the minute I turn the water off and begin drying myself to such an extent that I actually consider not having daily showers!!

All the best to you all.
