Could Bruising On Leg Along With A Lump Be Due To Blood Clot?

I RECENTLY WENT TO THE HOSPITAL FOR CHEST PAINS AND TO CHECK FOR A BLOOD CLOT IN MY NECK AND AROUND MY HEART UNFORNTUNLLY THE DR DID NOT FIND ANYTHING WRONG BUT NOW MY LEG IS BRUISED AND I CAN FEEL A LUMP IN IT AND ITS SORE TO TOUCH COULD IT POSSIBLE BE A CLOT IN MY LEG. THE DR DID GIVE ME A LOVEINOX SHOT IN MY STOMACH .
