I have been having dyshidrotic eczema on my left hand finger since 8 years, i have visited to many doctors and had tried all types of medicines and ointments to get rid off this terrible disease but i haven't got any positive result. at first it was just on my middle finger but now it's extending by n by to other fingers and on some area of palm near middle finger. sometimes all blisters get disappeared but after a week or month it comes again. i am really fed up with this disease soi am consulting u for the 'narrow band uvb physiotherapy' because only this treatment is left which i haven't tried yet. so i want to know is it possible to get treated by narrow band uvb phototherapy if yes then kindly share all the details of this therapy and its time duration and cost. waiting for your response thanking you
