Fell from a chair...

Guys its been 2 months after my ACL reconstruction on my right knee.. but it is still swollen and stuff. have had 2 aspiration before on the knee. but to no avail. Any idea what could be the reason?
Anyway guys i had a fall from my chair ytd. i sort of landed on my back or butt area. but no injury substain (well to that i can feel of) however i notice a really bad ache immediately after the fall, in my calf area and ankle area of my acl operated leg and sometime i feel the ache inside my knee as wel.. Is there any ways for me to check if my graft is still intact. and how shd i feel if it isn't??!!? need help seriously T.T

hi,
apply ice packs to decrease pain and swelling and consult your orthopedist soon
