I RAN INTO A TOOLBOX AT NIGHT, THE LARGE ONES THAT GO ON THE BACK OF A PICKUP TRUCK. MY RIGHT SHIN HIT IT PRETTY HARD. THAT WAS ABOUT 6 WEEKS AGO. A LARGE KNOT IS STILL THERE. I HAVE TRIED TO STAY OFF OF IT AND THE KNOT WILL JUST ABOUT GO AWAY. BUT AFTER WALKING ON IT DURING THE DAY , IT SWELLS UP AGAIN. IT HURTS ALITTLE SOMETIME. I AM 56 YEARS OLD. EXCELLENT HEALTH, STRICT DIET, STILL LIFT WEIGHTS. VERY ACTIVE. THE BOTTOM OF THE KNOT IS ABOUT 3 INCHES UP FROM MY ANKLE. IT IS SLIGHTLY TO THE LEFT OF THE FRONT SHIN BONE. I CAN WALK WITH NO PAIN, BUT AFTER I SIT DOWN THERE IS A LITTLE THROBBING PAIN THERE AND IT GETS BIGGER. I DON T KNOW WHY THE KNOT WON T GO AWAY.
