Hi, Kathy--
I have heard that there is an association. I may have heard that from Quix, but I can't remember, of course, where exactly I picked it up.
It's odd that Premarin would flare your symptoms if pregnancy, especially late pregnancy, is supposed to suppress them (I'm thinking of estrogen load; it is sequestered somewhat by proteins during pregnancy, but if I remember correctly, folks aver that it's the extra estrogen that confers some relief from MS)...
