Spent couple of months bed ridden due to instant weakness of my leg. I could only pull my leg forward by inching my toes forward. Finally I went to a low cost/free hospital/clinic to get help because I had no insurance. It took months to receive the help I needed and by then, I was already starting to feel better.
Physical therapy got me to walking again but remember feeling a weird feeling in my knee but ignored it. I remember mild inflammation in foot and ankle but it was so mild and would come and go that I figured it was irritation from my leg and not having walked on it for months and months. The pain in my hip had nearly gone away but not quite.
