I just went right over on my ankle working out. Sickening crunch and angle, gave out from under me.
I have weak ankles like a fawn lol, inherited from my dad.
Can't tell what if any damage is done yet.
I am terrified. If it is injured, I won't be able to work out.
Fear doesn't begin to describe it. I need it, it's the thing that stands between me and a mental collapse. Depression and anorexia, if I can't work out I'll fall back to where I was.
Also I can't gauge the physical pain because the emotional pain is raging.
Can't let my mind go there.
Any positive vibes you could spare would mean the world to me right now.

Try raising your ankle above your heart, ie rest a few pillows beneath it. Use ice bath with water for 20 seconds then transfer that to a warm bath for 20 seconds then alternate. If it is too painful to walk on the next day please go see a doc for a possible xray as hairline fracture may have occurred. From experience breaks are less painful than ligament/tendon tears. Also break only 6 week recovery as opposed to several months if ligament damage. The fact you heard a crack may be an indication something a little more serious took place. The sooner you get it looked at the better.
