I hate mystery injuries. Sorry to hear about that. Mine was my own fault. I was in a motorcycle accident. Ended up going down the freeway about 70mph without my bike lol. Spent a couple years in a wheelchair and crutches, a couple of reconstructive surgeries. Now I can't walk through an airport without a doctors note LOL. It has been a struggle for sure, but that which does not kill me.... So primal has been a SERIOUS boon for me, I am able to loose the weight and work out at my own pace and still see the results. Glad to see you were able to work out, don't let it get to you. I know how it is, been nearly 5 years and I am just begining to see the results.
If you don't mind me asking, what did you do to your leg? How long are you going to be out of action? I have been working out at home just doing little things, because of my leg and weight it is difficult for me to do a lot, but I am stepping up my routine here as of today.
