Also, just to clear things up, I don't think I was specific enough about this: This is not a current issue but one from the past. I haven't been on those types of medications in years but I remember the side effects and was curious to know what it was called and why it happens to people, or if it was rare or common. Thanks to those who answered. My current doc is the same one who I have had for a few years (the one who said he didn't know), and the same one who prescribed one of the other medications -per my own request, even. It worked flawlessly for the previous year with no problems so it just took me by surprise and raised a huge red this-isn't-right flag when I went back on it and suddenly started having that weird reaction. He is still my doc but that's going to change soon, too, as he is moving out of the state.
