I swelled up the last 3 months. I remember the first time .I noticed my feet/ankles were swollen. I was horrified. By the end .I could only wear slip on shoes, because even crocs (gross) and flip flops were too tight. I went in to have my son barefoot, because nothing fit.
For me having one of those inclined platforms under my desk worked wonders and any good employer will get you one. I still use it.
Drinking loads and loads of water and staying away from salt is important. Put your feet up when you can. As massive as my feet and ankles were, my bp was always low low low
