It is very interesting to note that, so far, the indications seem to be that a virus or infection is suspected as the main trigger for lupus. It certainly was for me. I caught mumps as an adult, in 1969, I was very poorly with it and really never fully recovered. With hindsight, the tell tale signs of lupus started straight away, but lupus was not diagnosed for another 10 years. During this time joint inflammation caused multiple joint deformities. Thankfully diagnoses come a little earlier these days and modern medication is much improved. We must still strive to raise awareness!
