Hi from Canada
This will not be pretty and could be life changing…but this could be what the problem is
My son was 4 yrs and was complaining about sore feet, it got so bad that we had to use a stroller when we went anywhere, anyway I took him to a Medical Clinic were the doctor examined him, he was diagnosed as having growing pains, I said ok
However the next day there was no improvement so I went to work and my wife went to the hospital they did blood work and we were in the Children’s hospital that afternoon as being diagnosed with Leukemia therefore is our story, still dealing with it after 4 relapses a BMT, radiation Twice, and his spleen removed.
Hopfully this is not the case but it is a rare indication
