Since you have a doubt about the medical cuneiform, I will advise for an x-ray to provide us assistance for confirming it. As from outside look, it is difficult to give an accurate diagnosis. Also, in most kids below age 15, there are complains about pains in the legs and foot at many times. This is due to vitamin D3
deficiency and calcium as the kids of today's generation are less prone the play outside in the sun. Having vitamin D3 and calcium medicines under the guided physician should provide pain relief.
Also, I will request to look out for flat foot
symptoms, as most kids in their development stages may have some minor symptoms which cannot be noticed easily.
Make him play in the ground more and this will help in vitamin D supplement directly via the sun.
Hope I have answered your query. Let me know if I can assist you further.
