I have a white line, a kind of long bump under my skin on the palm of my hand, near the base of my index finger. I had pompholyx a few years ago, and some small red blister like spots are also appearing on the insides of my finger (the same finger) - could this be the pompholyx reappearing? I have also had exczema on and off for many years, which also seems to be reappearing on my hands and forearms.
