also struggling with this, for first time ever. Came on suddenly 4 weeks ago after some 3 weeks of regular running/long distance walking.
I have a very weak ankle same side, which I had to have ligament restructure surgery on about 20 years ago, it’s never been the same since. I wear a support, but seems as a consequence of increased activity it’s caused pf.
Extremely painful, like a burning sensation in heal. Reduced to a hobble in mornings, but ok once I get going, but after 2 miles or so it comes back on. A lot worse in my work shoes.
I’ve also always had lots of problems with tight calves, which I imagine is a contributing factor.
Was kind of hoping it would just go with some stretching and massaging, but getting a bit intolerable now, so considering going to GP.
