I had injured my knee in April, Initially I had fallen on the knee, second I twisted it in my bed, while lying on my side the leg remained straight caught in the sheets, and 3rd while I drove I braced the foot on the floor (left foot) and the pressure I placed on the foot further added to the injury. This injury is lingering and was diagnosed as a knee contusion. I have pain on the lower part of the knee and just below, and stiffness is constant. Is there any info you can also provide. Thank you.
