FWIW, I also have experienced a similar itch. Most of the symptoms also sound very similar (never on the face etc). Haven't had one of those for a few months, so I am not able to recollect more details about this though. I too finally settled on trying to ignore the itch as much as possible. It lasted for only like half an hour after the showers, so I was not motivated enough to dive deep to figure out the root cause. Possible causes may include - Chemical composition of the water you use, Soap/Shampoo etc. It was suggested to me that the borewell water that we use may be the culprit, but since we have multiple sources of water at home (well / borewell / public supply) and since I did not bother going more in depth to figure this out, no clues on this front yet. Also, I have had the same problem at least a few times in another city as well.
