    What is causing small blisters/bubbles forming all over the hands?

    Hi, about one and a half weeks ago, my little sister had an allergic reaction around her eye/eyelids. It wasn't too long after that, she started developing rashes and small spots all over her right arm. It then continued to spread to her hands, but instead of small red spots, blisters or little bubbles started forming which are the colour of her skin. Its been about 5 days now, we have currently tried anti-histamines and soaking it in a vinegar-water solution. However, it does not seem to be getting any better. Is there a chance you guys could explain what it could be, recommend me a dermatologist? Or possible solutions?

    Reactions can take weeks to subside. I use pinetarsol a lot for my children and any reactions they have as it is eczema friendly. If your sister was fighting a virus off at the time it could be molluscum warts which are a virus, they are skin coloured and contagious.

    This sounds pretty serious, but my overall impression at the beginning is that you should not be soaking her skin in a vinegar and water solution. If she has an irritant component driving the lesions on her skin, introducing acetic acid is very unlikely to be particularly helpful and may make the situation worse. If there is persistent destruction of the barrier of the skin, then that also opens her up to a risk of infection. So in the first instance, I would recommend not using vinegar and water solutions. At the outset, there are a broad number of causes for the current situation, but it would be worthwhile seeing either a dermatologist or an immunologist to take a proper history and do an examination. The kinds of treatments they might recommend would be topical moisturisers and topical steroids. A number of infectious causes could also be contributing to this, including HSV and varicella, as well as molluscum, as was mentioned by another commenter on this post. Ultimately she requires specialist assessment.
