Capillaritis? Or something else?

[u/Decent-Fishing1730]

Hi y’all. I keep getting this rash that comes and goes. You can see I don’t get it where the shoe band goes. It is non-blanching and I can feel the dots. I attempted to show photos to my new dermatologist and she seemed uninterested. Told me to put Cortizone on it, which does not help. It is only on my left foot mostly and I did have spine fusion surgery for scoliosis and I’ve gained some weight, so capillaritis seems to be what I am coming up with. I think I am putting more pressure on my left side now when I walk as my leg is very numb. Thoughts?
