had left hip replacement surgery little over 2 years ago in November, am 52 years old , good health yet a bit overweight but have had no problems with it until now. Started top feel a bit sore beginning of last week, gotten progressively worse to the point that I can hardly walk on it now, also swollen and throbbing in the area of my surgery. Going to go to see my orthopedic doctor on Monday, yet wondering if I should go to emergency now.
