Welcome to our forum.
Hey Rick I had the same problem too. I went to my doctor and he said what I had was caused by very dry skin. This was because of the winter months and being in the hot water it will bring that out. He gave me something to put on it and told me what kind of soap to shower with and since then it has gone and I can still enjoy my tub. I take a shower when I get out put the cream on any spot I see and so far so good. I also changed the time I put the dichor in so it was a few hours before I went in.I would'nt fool around with it though. Ask your Doctor to check it out first. I read a few things here and it gives you an idea of what it could be but everyone is differant. Its better to be safe than sorry. Hope this helps.
