My wife has rheumatoid arthritis and despite being on enbrel she occasionally gets a flare up (usually in her hands and wrists) Would Flameout be ok for her?
Does anyone know anything about DMSO and joint pain?
I would be interested in this too, as my girlfriend also has RA.
Maybe you can ask in this thread:

She seems to know her stuff 
There’s a good and growing amount of data supporting the use of DHA and EPA to relieve some symptoms of rheumatoid arthritis.
While there isn’t a listed drug-supplement interaction with the two (Enbrel and DHA/EPA), I’d have her discuss it with her physician before using the two.
Hope that helps.
