Ankle and knee pain

[JaCqUi123456]

Two weeks ago I had an accident, I feel off a Quattrocycle and the wheel ran over my ankle twisting my leg. Bruising came out straight away and a little swelling, I rested leg for a few days and continued walking with a little pain thereafter . However fast forward a week on and I started having shooting pain from my Achilles heel and up my calf every time I walked, this also put pressure on my knee joint thus causing more pain( I have no knee, as this was taken out in 2001) on top of this, my leg feels heavy with tingling/ pins and needles sensation when I rest it...? I have been to my GP, who inform me rest using the " RICE method " I have for three days, on the forth day I went out and once again had shooting pains from my Achellies heel... I visited my local A&E, had an x-ray, which confirmed that's it's not broken ( knew it wouldn't be) Told it was sprained ( in a not so nice way) and to go home and take painkillers!!! On pushing this, so I can at least walk, they placed a bandage on my knee ( not ankle) and gave me crutches... pins and needles, dull ache and heavy sickly feeling is still present as well as not knowing what to do... please help or advise
