I fractured the base of my 2nd metatarsal in my foot 7 weeks ago. I feel like it is taking forever to heal. My doctor has me in a walking cast but for the most part I am still having to use the crutches. He told me over the last week to start weening myself off the crutches but that I would be in the walking cast for an additional 4 weeks. I still cannot put much weight on my foot and my foot is still extremely swollen. Is this normal after 7 weeks or do I need to seek a second opinion?
