Doctor, my knee has started to oscillate and my femur is getting soft. Does this mean I have allergies?
It's probably dropsy. You will need to have arthroplasty and possibly a miracle cure. You should also eliminate oyster on the half-shell from your diet.
You may find yourself lying around in bed occasionally over the next five weeks. Call me if your knee is still oscillating after that.
