Hi yesterday evening I was playing with my dog and her rope knot, as I swang the rope the knot hit the outer side of my inner knee, the stinging pain was weird, and a big knotty vein appeared very dark, we put ice on it and it calmed down, Today I have the bruise the size of a ball, plus my lower calf is aching, my knee feels like it has cramp and I have upper leg pain going into my groin, and a slight pins and needles feeling. I have been elevating the leg when I can but I work 50 hrs a week as a chef. Any ideas.
