Hi I’m getting tests done at the minute by GP for a range of autoimmune and muscle connective disease. However I’m convinced I have dermatomyositis as for years I have red knuckles. They are not raised or cracked just red but do sometimes burn in extreme cold and get cracked. The redness disappears when blanched. Is that normal for gottrons sign or does blanching mean it’s not gottrons sign? I also have redness on the skin of my fingers as well as my knuckles. I’m so confused and worried. My CK levels have come back and are clear so now waiting on autoimmune and anti nuclear blood tests. Has anyone any advice please? Thank you so much and I’m so glad to find this group as Dr Google has only made me anxious!!
