I had B12 anemia that may have been caused by chronic GI problems (malabsorption) &/or chronic inflammation. I was Dx'ed in 2000 with the SCLE subset of lupus. Within a short time of starting Plaquenil, most of my chronic problems, incl. the anemia, started to improve. I've read there are dozens of types of anemia, though...
There were times in the past I had very elevated WBC, probably from active inflammation. This started when I was a teenager (am post-50 now,
My rashes were on my torso/upper arms: nonscarring target-like, typical of SCLE with anti-Ro antibodies. Your skin problem is obviously on your face, so I probably can't say anything very useful rash-wise. (Sorry.)
I know others here have discussed anemia, so I hope some of them will chip in soon, too. Best wishes, from Vee
