I didn't see the picture but I am sure it wasn't pretty.
I hope and pray that you heal up without any residual problems.
I found a cure(almost) for that kind of injury years ago.
I try my best to keep both feet on the ground.
( as I typed this last sentence the memory of me laying on my back flashed back in my mind.)
I was walking out one evening with my Pacseat on my back, I tried to walk across a mostly dry creek bed over a pile of drift wood. My foot slipped and I ended up on my back like a turtle. I was kind of stuck for awhile as I couldn't sit up or turn over. After a bit of struggling I laid back and enjoyed the humor of the situation.
I'm glad you weren't hurt any worse.
God bless,Mudd
