Good news.
I'm circa 6 weeks behind you.
As a comparison - we are all different aren't we?
Pain in foot - like you it only aches on the outside and clearly due to strain when I've done too much. My main pain is in the opposite knee, my first indication of problems as I'm possibly limping a bit still. I've traced that to a ligament attatchment so should eventually settle. I still cannot believe I put up with so much pain and its now gone.
I walked 6 miles yesterday, but needed to sit due to being a bit knackered twice. My walking speed is now up from 2.4 MPH to 2.8MPH but only over less than a mile after which I have to walk slower.
I can stand, walk, lift stuff etc at the allotment now for up to 2 hours at a time, definately better than before the op.
I'm not doing any exercises, definately no rotation, I found all of that was making me worse. But I'm working on my balance by walking foward and backwards [its lumpy underfoot at the allotment] and up & downstairs, all of which has come on a lot in the past two weeks.
Being out and about in the day mean being more careful at night or vica versa. I think it will be properly fixed when I don't have to consider this any longer & can walk at 3mph without being done in quickly.
Feeling very thankful to be on the other side of this and improving.
