Found it -
I think the poster confused that the '98 incident was cited in a piece from '07 that was picked up, with it happening twice.
As far as I can see, it was a one-time event, apparently related to plane flights, that was resolved and she's not on any drugs related to it and hasn't been for some time. Doesn't seem like it'd be related to the current issue except that perhaps inactivity has done this to her twice, fifteen years apart? Lesson - Hillary cannot stop moving! To wit -

She approaches her seventh decade with what any 60-year-old wants most - good health - but Clinton recalled a potentially fatal scare in 1998.
It came while she was campaigning on behalf of Chuck Schumer's New York Senate bid and a swollen right foot caused her terrible pain. She thought she just needed to slow down from constant flying.
A White House doctor told her to rush to Bethesda Naval Hospital, where doctors diagnosed a large blood clot behind her right knee.
"That was scary because you have to treat it immediately - you don't want to take the risk that it will break lose and travel to your brain, or your heart or your lungs. That was the most significant health scare I've ever had."
Clinton said she no longer takes blood thinners and otherwise has enjoyed good health while zig-zagging across the country for the past nine months, keeping a schedule that exhausts aides half her age.
