Re: Lupus maybe
Deddleman, there are "subsets" in lupus. The classic kind is Systemic Lupus Erythematosus = SLE. There are sticky posts (permanent info posts) at the top of the thread list [look for padlock symbol]. 11 diagnostic criteria are laid out, of which you typically have to meet at least 4 to support a Dx. These don't have to be met simultaneously, meaning can be met over time. Two specific autoantibodies are considered very diagnostic---anti-ds-DNA and anti-Sm---but there are perhaps a dozen or so others possible. SLE favors women by a ratio of about 9 to 1. SLE is treated with antimalarials, steroids, or immunosuppressants; UV avoidance is sometimes necessary.
Drug-Induced Lupus Erythematosus = DILE is another type, and tends to strike older people more often, male and female alike, because we take more of the meds that can trigger it as we age, e.g., meds for cholesterol and BP, and certain antibiotics (etc.) have been implicated (that's only a sample, there are many more). Different autoantiboies are characteristic of DILE: it features anti-ss-DNA [anti-single-stranded-DNA, as opposed to double-stranded] and anti-histone. The remedy for DILE is straigtforward: discontinue the culprit drugs(s) and symptoms will almost always resolve in a matter of months.
There are two other kinds, but they don't seem relevant to your question.
I have milder SLE & have done well on an antimalarial. Several years back, my SIL had a bad bout of muscle pain, fatigue, and neuro problems after starting a cholesterol med, was diagnosed by a rheumatologist with probable DILE, quit the cholesterol med, took Prednisone briefy, then recovered fully.
I'll stop here to let you mull, then I hope you post more. BTW, I think seeing a specialist is the right move. Are you seeing a rheumatologist? Best wishes, sincerely, Vee
