Waited until the end of the day, as I didn't want to jinx it lol, but had the best 2 'back to back' days I've had since the LIS.
Yesterday the adductor was the strongest it's felt, so managed a decent walk, and the only time I felt a burn was going up a small hill. Rectogesic when I got back dealt with that within about 15 minutes.
Today, though the adductor has been producing some weird nerve pain high up in my groin (referred?), I managed my longest walk so far (40 mins) admittedly still a stroll, but crucially no burning at all, and I went up the same hill as yesterday!

I think a key recently has been that I've consciously tried to rotate from standing, to sitting, to lying to walking etc every 15 - 30 mins whenever possible, to try and avoid overly stressing the injured areas.
I'm not getting carried away, as I'm still a long way off normal, but, f I can string another good day on to this tomorrow, then you just never know....
Right, off to wrap myself in cotton wool now and head to bed...
