A week ago I went to my doctor because I was having pain in my left foot,.lateral foot pain. It's been going on for about 6 weeks. It would dull ache most of the time with sudden bouts of extreme pain in which it felt like a knife was digging in my foot. He did an xray and said it wasn't broken and prescribed anti-inflammatory medication. A week later and now I can't bend my left knee back and it's hurting to put pain on my knee. Basically I was bent over pulling off my work boot and I felt something strain in my calf, not pain, just tight, and that's when the knee pain started. My knee is also ocassionally clicking and feeling weak. No pain really when I just sit, but getting up is excruciating sometimes. I'm an extreme limper these days.
