Kathy,
I have what I call plucked chicken skin, because it looks like a chicken that has been plucked. Or, it looks like I am really cold on my left arm and leg. Some of the bumps are bigger than others. My skin also has tiny sores. It clearly is not my normal. Unfortunately, I keep scratching. Because I cannot get in and out of the tub, I have a pan to soak my feet when I am in the shower (I sit in the shower). I use epsom salts as suggested by mrsD. I use the water to bath my legs and arms. I also use epsom salt lotion (also suggested by mrsD). I am not sure it is helping the skin, but I have hopes it will. I started this regimen to help my muscles (It is the magnesium I need so I have added nuts and more green leafy veggies to my diet). Aveeno makes a lotion for eczema. I use it every so often too. I even use Neosporin on the sores. The rash is stubborn though. So far it is winning.
