I broke my femur 4 months ago, had surgery where two rods were inserted, have been healing well, but now have a swollen right leg, primarily from the knee down on the leg where I had the surgery. There is slight discoloration on my ankle down to my foot, but the moderate pain is in the back of the calf. I had a DVT after arthroscopic knee surgery 12 years ago. I noticed the swelling after spending about 10 hours on a bus with stops and periods of walking last Wednesday. I m wondering if I should wait until after the holiday weekend to consult my surgeon or go to the ER. I am 67 years old and very active.
