beth, I don't remember the exact timing of when my feet first started to swell but I think it was just about when I started relying heavily on lomotil ???....
anyway, my docs were not overly concerned... they just put me on hydrochlorothyazide (??)... and it pretty much immediately reduces/eliminates the swelling...
I would stay on it for a month or so and then try to wean myself off the hydro....
over time, I have begun to transition to immodium from lomotil and as I use less lomotil swelling hasn't been a problem in quite a long time..... anyway, so long and short..?? my first impression would be don't worry yourself too much and talk to your G.I. or surgeon..... -Mike
