I have a problem which is causing great discomfort. I do not know what is te reason for it.
Pls advice for the following:
After showering or after washing my hands. I feel that's hands and feet and body ( basically skin) is slippery ( not oil slippery but slippery like when we have powder in our hands- like carom board slippery) this irritates me just like we get irritated hearing chalk sound on the board
