i have lymphedema in both legs due to my groin lypmh nodes removed, i wear velcto fastening shoes and trainers that allow me some room when they are bad, although there is not much choice with the velcro, is there any meds that she can get, i did use water tablets and they were great but the side affect caused problems for me, the swelling is worse at night so i have 2 pillows under my mattress to elevate my legs at night, if you type into google there is a few companies that sell velcro fastening breathable footwear.
