ACH, paronychia and Protopic

Hello and thank you for reading this. I’ve got a question about the use of Protopic for a condition which has been diagnosed as Acrodermatitis continua of Hallopeau (ACH).    

I have a painful, long-standing thumb-nail condition which looks like chronic paronychia (now with run-around abscess), as well as an associated skin problem. This extends to the joint and is characterised by flare-ups with tiny blisters which lead to peeling, stinging and scalding. The condition is ‘fuelled’ by moisture of any kind and both nail and skin have responded very well to some anti-fungal treatments, although this contradicts hospital test results, which have not revealed the presence of fungus (or bacteria, foreign body or malignancy). I don’t have psoriasis elsewhere on my body, neither is there any family history of psoriasis, but after many months of uncertainty my dermatologist diagnosed ACH. Protopic 0.1% helps to relieve the nail-pain, but it is less effective on my skin. For many weeks now I’ve been keeping my skin pain-free and in good condition just by keeping it bone dry.  

So here’s my question: does the fact that Protopic reduces my nail-pain rule out any possibility that this condition is chronic paronychia?

Your opinion would be very much appreciated. With thanks.
