Your current symptoms do not sound related to your original injury
. Pain that runs down the back of the calf into the toes often makes us consider nerve
entrapment in the lower back causing sciatica
. There are other possibilities of course but this would be important to consider in the diagnosis.
With regard to your original injury it would be important to have X-Rays of your knee to be sure that you did not fracture
your knee cap or the end of the thigh bone when you sustained your injury. Ongoing symptoms because of the injury should be investigated.
