I was sweeping the floor and I noticed that my shin suddenly burned and itched. I went to rub the area and had a egg size knot that was bruised on my shin. I didn t hit my leg or anything. now last week I had an angiogram, came home and did something I shouldn t have done and felt excruciating pain that paralyzed me for a few min. the next day I had bruising down the inside of my thigh on the side that was used and on my lower abdomen. I had it checked and the dr said I might have popped the seal they used to close the vein. now this. I originally went to the hospital with chest pain on right side and around my back. heart is ok, now checking my gallbladder. but what about this knot/bruise on my shin all of a sudden?
