My knees/shins, ankles, & feet hurt after exercising for 6 weeks. Why?
Please read description.
I'm in college and had to take an exercise class. Starting off, I expected to be in pain for the first or two weeks. All the pain went away for 3 weeks and recently when starting class, after 20 minutes I'm in horrible pain. It is only fast past walking. Nothing extreme. My entire leg(s) are killing me and I have to stop before finishing 2 miles. Causes?
