"Undiagnosed skin condition - Can anyone help?"

Undiagnosed skin condition. Have had this skin condition looked at by a doctor who told me I had contracted something of my husbands dog. He told me that this condition is not normally past on to people, I believe the phrase is not usually zootronic .not past through speceas. [phonetc speller dislexic] I have lost touch with the above doctor and now because this condition is rare, I feel I am being labeled insane by the medical profession. I have an impaired immune system due to past cancer treatment. Can you imagine what it is like trying to live with this and being ignored. Is there anyone out there that will tell me what this is and treat it accordingly? I believe I have picked up some type of lies. Is there a doctor out there that can at least tell me what to treat this with? If there is I would appreciate your help. thank you.
