This past Thursday I squatted, no
weight, but went deeper than I should have. I felt something sharp in my knee
, and it was painful. Since then my knee has been acting up. It's warm, but not swollen. I can walk without pain, but going up stairs it still feels a little weak. I am scared that it is failing or has failed. The reason why is that I am 6 weeks pregnant. My L5 and S1 discs in my back are completely deteriorated, and L4 is degenerating.
