Ok, so I had surgery about two weeks ago and anyways I had to have a cast put on my right leg from the foot to the knee. It became unbearably itchy and so I stupidly grabbed a spatula handle to shove down and scratch my leg. I knew not to put anything that could cause a cut, as to not cause infection; but I think I may have disturbed the material (gauze?) inside the cast and it's bunched up where it feels like a rock is being stabbed against my leg. It feels as if it's pulsing with like a heartbeat, so could it be restricting the blood flow? I read that it could cause a tourniquet-like effect. There isn't any noticeable swelling at this point so I don't know if it's affecting the blood flow but I don't really know.
