I had similar symptoms a couple of years ago where the pain radiated up and down my right leg. I also developed a knot on the left inside of my tibia. X-rays did not confirm what an MRI did which was a stress fracture. I also injured the muscles in that area of my leg. I did it with the "Terrible Too's" ( I think that is what it is called), meaning way too much distance way too soon. I took time off but did not get well until I dedicated myself to physical therapy. I still have the knot and have to keep my calf and soleus muscles well stretched. I also do to taps and toe/heel raises occasionally. Good Luck!
