I am almost sure I have a stress fracture of the right big toe but need some advise. First off, I plan on calling the ortho tomorrow so don't flame me and tell me to get in touch with the doc. The pain started after a slip and fall last Saturday on my run but it was just a dull ache that has now increased and caused a change in my gait during yesterday's run and last night caused me to not sleep or wake up a lot. There has been no swelling or bruising but I can pinpoint the pain on the medial side of the base of the big toe. Any body have a clue?
