Finished my week 9 run 2 with a glorious run on a cruise deck (first day of my hols), but the next day I had badly swollen feet and ankles. Doc says no running for a week. Whaaaaat? Feeling very very sad : ( I've been prescribed some sort of diuretic tablet and been told to drink lots. However, I've explored on the net and think it might have been brought on by a) the flight b) underactive thyroid (which I have). Anyone else had this problem?
