My 13 year old daughter started getting white itchy lumps on her fingers knuckles and hands with turned red and led to terrible scaring. The doctor had not seen anything like them. With in a month she had terrible allergy symptoms, hives(big) and wee itchy spots and swollen feet, hands and eyes. Doctor sent her to skin speciallist 2 weeks later we find out she may have some sort of arthritis or Lupus due to positive ANA. Week later she devlopes photosensitivity. 2 weeks later we are waiting to see a specialist to find out if there is any more damage and work out what she may have. I think that doctor said she had the double-stranded DNA without the andibody. I know it is not much to go on at the moment but I just want some possibiliies of what it could be so the outcome will not be so daunting.
The skin condition you describe could certainly part of lupus but could also be due to many other conditions. The ANA testing as well as other blood work will be helpful in making the diagnosis.
