Hi, iv'e been on ESA work related for around three years now due to a condition known as Avascular necrosis. I have had one hip replaced and am now awaiting the other to be replaced, however i suffered with depression after the first op and feel like postponing my pre op. My worry is if i do this will my benefits be stopped? I'm due my next review in june this year. My personal adviser is phoning me up every month asking if i'm anywhere near my date for surgery. Thanks in advance Brian.
