Thank you doctor,
There were no blisters, but the areas that are red feel very lightly swollen. There was no pain prior to the appearance of the rash. She had a very similar rash on her hands multiple times over the course of the last few years and there were blisters. But, it is unclear if those two symptoms are related. The white residue seen on the pictures is pain-inhibiting salve that was applied in an attempt to self-medicate.
