Re: no joint pain?
Hi. I just checked my hardcover for the statistics:
80% to 90% of lupus patenits have arthralgia (reported joint pain); and
less than 50% have arthritis in joints (pain PLUS visible swelling); and
10% have joint abnormalities associated with rheumatoid arthritis (deforming).
I had various things wrong since early teenage years, stuff that now looks like a gradual build-up to "subacute cutaneous LE" (SCLE is a "subset" of SLE). Joint pain was one of the last problems to appear, which didn't surprise my rheumie. i.e., joint pain doesn't have to happen from the get-go.
If you review the "4 of 11" ACR criteria [see the "sticky post" at the top of the board], arthritis is only one criteria of the 11 listed. You need any "4" over your LIFETIME to be Dx'ed with systemic lupus. So it's not a "requirement", per se; meaning, you could have some OTHER "4". Hope this helps. Best wishes, Vee
