That's such a pain! I think saying you could run again may have been a bit premature...hard to say it's different for everyone and some people on this group have said they're able to run again but most can't, I know if I tried to run, after a few steps it'd give way...plus my surgeon said from the start to me, whether or not you are capable of running you probably shouldn't ever run again because the excess force and it'll keep making the OCD worse and causing damage.
I think physio and orthotics are probably a good conservative approach to take before you decide to undergo surgery again and it might help a bit or a lot but probably couldn't hurt anyway! Physio didn't help me at all but my surgeon said my legion is way too bad for conservative approaches to work. Everyone on here is different though, results vary a lot!
I totally feel your pain(literally) I used to be so sporty and now I feel so crippled, I spend half my work day limping on one foot, which then starts to hurt so they both hurt! This disease really sucks!
