Eczema or Psoriasis

DH has been battling skin allergies for some time already. He was always told that it was eczema and had been prescribed with all kinds of treatments for eczema from creams to tar and even strange prescriptions such as special water! However, when he recently went to see a doctor here for a flu, the doctor expressed some interest in his skin condition and told him that it might actually be psoriasis instead of eczema and if it was the case, the treatments he was using previously may not work. Perhaps it is a good time to get it checked out to ascertain what it really is.
