Update here. I've got an appt at end of March to see a urogyno.
I'm about 10kg over what I should be so GP suggested I try to get back to my usual weight before appt as extra weight doesn't help the issue. In a way I'm happy....being told to lose weight means ill try harder (stupid isn't it) BUT attempt one today of walking, just me, without a pram and I'm now crippled. Feels like I've run a marathon, down there only! I can't lift my legs to get upstairs to bed without pulling on the railing. It's so achey/heavy and uncomfortable. Catch-22!
Can't wait for the appt to see what she suggests....until then time to shed some kg.
