I highly recommend talking to your doctors

It sounds like there is no clear diagnosis of what the rash is, although the fact that it responds to steroid creams suggest that it might be a skin allergy or eczema. Although it is unlikely that the rash is related to a larger medical problem, this is certainly possible, and some liver disease are associated with rashes, for example.
More to the point, you should not keep applying strong steroids like fluocinonide to sensitive areas of the skin, such as the face, for long periods of time without being followed closely by your doctor. This is because these strong steroids can thin out the skin over time with too much use. Also, using strong steriods especially on the face can sometimes, oddly enough, cause a different kind of rash (especially around the mouth) that clears up when the steroid is stopped. Finally, chronic use of a steroid cream that isn't working well can be due to tachyphylaxis, a phenomenon in which the cream stops working and the rash rebounds worse than ever.
Your doctors will be able to take a look at the rash and help you decide what to do.
