I have hashimoto’s and am 3 weeks into a t3 only trial because thyroxine doesn’t seem to agree with me (long story). I was on 150 t4 pus 20mcg t3 at xmas but got hyper symptoms so t4 reduced to 100mcg. 2 stone weight gain since xmas. Have had ankle swelling for ages but since stopping the t4 and switching to 60mcg t3 the swelling is getting worse. My feet and ankles are swollen, the left foot is worse. Legs are stiff and tight so swollen too. Fingers stiff too. My ankle knee and wrist joints are painful and my left ankle aches. My left foot can be very painful. GP prescribed diuretic which is not having any effect. If anyone has got any suggestions I’d be very grateful.
