Dr. Google Diagnoses

So I know it's not good to self diagnose...but I thought I was crazy. Here is the thing, if I wear heels with a closed back, I automatically get blisters. But that didn't use to happen. I have these little round bumps on the backs of my heels. They are hard like bones. I have lost a LOT of weight in the last couple of years. I attributed this to finding lots of bones in various areas I didn't realize I had and are now much closer to the surface.

But lately it's been bothering me more and more. And I'm all, this cant be normal. But what if it is and everyone thinks I'm crazy. So I did what any one I would. I asked google. And google did not fail me!

I have Haglund's Deformity . I am almost 100% positive this is what is going on. It must be aggravated by the fact that now I walk almost everywhere, whereas prior to my Brazil life, I drove everywhere. And I'm on my feet in school during classes most of the time, particularly with the kids. So I guess the first thing I'm going to do is go find some heel lifts (anyone know where I can get those? Or what the name in portuguese would be?). If that doesn't work, it's off to the docs for me!
