OMG I can't believe what have n are going n through. I give you immense credit for hanging in there n persevering through it all.
First, you need yo get an attorney. To me, it seems you have a malpractice on several levels.
Secondly, you will be able to walk with assistance of several aides - a shoe with a lift after your leg is measured for length deficit. You will probably eventually need to use a crutch or walker indefinitely. Thirdly, depending on which leg with deficit, you'll be able to drive but with hand controls.
Life will be different but you'll still have a life. All.if us on this blog, in one way shape or form, have life an manage to get through it daily.
You're a strong person to get this far. DON'T GIVE UP.
Oh most importantly, you need to have a sense of humor. Studies have shown people who can laugh have better outcomes. So you hang in there. We're all here rooting for you n can sympathize with you.
