Dead leg after c section!?

Sammy
Hey, 
I had my second c section almost 7 weeks ago, around 2 weeks I was sent for a dvt scan due to a pain in my calf. Suffering with high blood pressure at the time the midwifes wanted to be sure as was concerned for me... However. Dvt scan showed no clots so they wasn't sure what this " dead leg calf " feeling was... 
Anyways, this feeling is still present, if not worse, it's worse on a night, feel like my calf is a dead weight as it feels so heavy. I've also experienced a numbness at the same side but in my bum cheek. 
I'm really worried about having a blood clot and the dr not finding it. He checked my
Leg last week and said it was fine but I'm not so sure 
Has anyone else experienced this?
