I have no experience with swelling related to medication but I felt compelled to respond because I feel like I get anxiety-related swelling in my face (lips, eye area, throat), feet and occasionally on other parts of my body. I can't find anything to confirm that anxiety may be the cause of this, but the "outbreaks" always follow periods of high anxiety. The swollen areas get slightly red, itch and ache. If anybody knows anything about what this may be, I'd like to know.
