I had a lot of leg heaviness which improved around week 7 after chemo. Turns out also I had reduced cardiac output so once on medication for that it improved dramatically so please get checked out. My cardiac function has returned to normal but I still have some ankle puffiness which might be more related to my weight gain now.
Ankle and foot pain can be a symptom of an aramatose inhibitor. Have you started one of those? I had very bad issues in the morning initially but it has improved a lot 12 months on.
I took panadol osteo for 4 to 6 montbs post chemo due to pain but suddenly didn't need it anymore.
