Eczema??: If you indeed have eczema it is almost always bilaterally symmetrical. If you have a patch on the right hand side you almost certainly will have an equivalent sized patch on the left hand side. Very commonly it shows up in the flexor creases of the elbows and behind the knees. Dry conditions exacerbate it so get a good moisturizer and smear it on when soaking wet, post shower. Most don't use them
