I am one week post right hip replacement surgery.  Since waking from surgery, experiencing numbness, in right foot and ankle.  While numb, I also feel constant needle prick sensation over entire area.  I am unable to flex the foot upwards which results in drop foot when walking on walker.  Will see surgeon in two days to examine the situation.  Until then, he has ordered nerve pain meds 3 times a day.  Need to talk to anyone who has experienced this and what I might expect down the road in my recovery.
