I use epiderm for sore itchy fingers,I also have an allergic reaction to some jewelery including an antique 18ct gold ring,which is now rhodium plated,but too early to say if it has cured the problem.My right palm is now extremely itchy with little bumps/sores,nothing seems to alleviate this despite using lots of moisturiser .My left hand is only very slightly affected.I am right handed,57yrs old,have B12 jabs quarterly.
