After six months there should definitely be no pain in your leg from the procedure. I would go and see your Doctor to make sure everything is ok. After the procedure, they put a slowly dissolving seal on the femoral artery incision which takes 90 days to completely disappear. I have read some reports where the femoral nerve has been slightly damaged during the procedure, giving discomfort, but this has resolved itself in nearly all cases but can take a long time.
