Pain under knee cap

I had my acl reconstruction surgery (left knee, also mcl and cartilage repair) on the 27th of October, 2009, today
16th of November I am able to bend it to 127 degrees, but when i do the exercise where i place weights on my ankle and lift the lower part of my leg i get a pain below the knee cap. Is this normal?
I am still walking with crutches and using a brace. Wearing the brace hurts the upper thigh and when I stand after sitting for some time i get an extreme feeling of pins and needled on the
inside of my thigh above the knee, also the bone on my knee right side hurts
when i press on it.
