I went to Urgent Care today because I fell and hurt my ankle. My ankle is very swollen and I have numbness in the bottom of my foot, however, I did have an x-ray and the doctor said no broken bones, just a sprain. They wrapped my ankle and gave me a foot brace, but it hurts so much when I try to walk. My question is, should I follow up with my own doctor and could they have missed a hair line fracture?
