18 years old, no recent surgery, always on my feet, no recent long trips... Bumped the front of my right leg right there on that bone at work and it bruised two weeks later there's still a knot there but yesterday I had a pain on the bottom of my foot every time I walked on it, tonight I have a little pain in the back of my right calf but pain in foot is gone I'm so scared I have a blood clot so I have my heating pad wrapped around my leg!! No swelling or redness! Can somebody help before I have a nervous breakdown?!
