question: I have a persistent problem with a rash that itches sometimes - and it just  partly covers three fingers -  from my index finger to my ring finger and a small  area below my index finger too on my left hand only. This rash dosent reach the finger ends. there are tiny 'blister like spots that  seem to break out now and again.  But is underlying most of the time and is quite uncomfortable. I have tried various creams and antiseptics  which help the initially - but the area goes very very dry and the skin is quite hard .
