They are both Calcium channel blockers, as someone with no medical knowledge that would make me ask GP the question. Have you discussed alternatives with him/her.
Cupotee, it's a well known side effect for some people. I've been taking it for about five or so months and my GP warned me about it.
I've found that by keeping my feet up on a small footstool every time I sit down really helps stop it happening. I too was very disappointed when my ankles and feet initially swelled up but if you keep them raised whenever possible the swelling will stop. Mine have gone back to normal.
I take ramipril too, have taken it for about ten years. This felodipine is a fairly recent add on as my blood pressure had been slowly creeping up and I'm on the maximum ramipril.
Good luck :)
