Topaz Surgery

Hi, I’ve had Plantar Fasciitis in both feet for almost 5 years and three weeks ago I under went Topaz surgery on both my feet. For the first 2 weeks I tried to stay off them as much as possible and when I did move around the pain wasn’t too bad. After meeting with my consultant he advised being on my feet more, I have taken this advice, however both my feet are now very painful and I struggle to be on them for any length of time. I am still taking painkillers but even they don’t seem to dull the pain. Did anyone else experience this with Topaz Surgery? Does anyone know how long this pain should last? Thanks in advance.
