"The acute pain that you may have felt immediately after the injury will decrease with time, but in the weeks after your fracture, some pain may continue and this is called sub-acute pain. This is mainly because the lack of movement that was necessary to help your bone heal has caused the soft tissue around the injury to stiffen and the muscles to weaken. In addition, scarring and ongoing inflammation may have developed in the soft tissue while the fracture was healing, which can also make movement difficult and cause pain."
Yes, it's normal, as you suspected. I broke my tibia and fibula in a motorcycle accident when I was 18, and despite my youth, it took years for the pain to completely disappear after it healed. As Len's excerpt states, there was severe muscle atrophy in the affected leg. It took a long time to equalize the strength in my legs, not only because of the atrophy, but because the unaffected leg was greatly strengthened by walking on crutches. Bear this inequality in mind as you continue to train, because maladaptations due to injury can persist for ages, and often create new problems of their own. You will eventually get over it in time, but I would recommend targeted physical therapy to retrain the injured leg as soon as possible.
