I injured my shin last Saturday. When I came home from work on Tuesday, I noticed that there was a lot of blood pooling in my foot/ankle. I went to the doctor for an x-ray on Wednesday which showed no fractures. However, as of today, the pooling has gotten worse, the pain has increased, I am losing movement in my ankle/foot, and I am losing sensation in my foot. Is this something that would require an ER visit or should I wait? I don't have insurance, so medical care is not easy for me to receive.
