i have had a rash for about a month and a half now.
it first started on my legs then spread to my stomach and chest now its also on my arms and back.
i went to the doctor and he did a biopsy which came back inconclusive however he is convinced its erythema multiforme (as is the other doctor he works with). he believes its autoimmune however we cannot seem to find a cause. i had some tests done and my kidney and liver functions were fine, my full blood count was normal and i had a slightly elevated Rheumatoid factor.
hes ruled out an allergic reaction to an infection or medication.
ive also been having fevers randomly, some joint pain and fatigue (needing to sleep like 12 - 14 hours) and also some insomnia where i am absolutely exhausted but cant get to sleep and some gastro symptoms.
has anyone else had this rash? if so was it caused by something autoimmune?
