I just noticed today when I woke up that I have some sort of rash on my hands. The rash is located on my right index finger and my left hand and index finger. On my right index finger it seems to be slightly swollen. There is a small blister on my right index finger as well. It just looks like red spots on my left hand. It does not itch at all, but it does burn when touched or in contact with warm water. Is there a possibility of it spreading or is it contagious? I have done a little research and assume it is some sort of contact dermititis, but I have never gotten it before, and cannot think of anything that I new I have come into contact with. Any helpful info would be much appreciated.
