What causes swelling in my ankels and legs?

The medicines that you've listed don't usually cause swelling in the ankles & legs.  In fact, furosemide, sold as Lasix, is supposed to help you get rid of excess fluid/swelling.  

Heart failure, kidney failure, and/or liver failure can lead to swelling in your ankles & legs.  So can venous insufficiency, eg damaged blood vessels, typically from blood clots.  Gravity can do this in just about anyone who stands on his/her feet all day long.  Of course, trauma can cause swelling.  So can infections.  Acute blood clots can do so (as well as lead to long-term swelling).  Consuming too much salt might aggravate the issue.

Best to chat w/your family physician and express your concerns.  Good luck!
