[|Human|] I hvew have psoriasis on legs . If not touched, the pimples tend to heal , but same  time causing a big deal of itching , and  once touched again, the sores  show up with more threatening    signs .Am I right , that  if  untouched , these shall vanish in a natural  way ? ( ie., without  need for  steroids ? )
