[|Human|] My son went to the dr a few days ago and had a xray because his leg was swollen and sore to the touch. They couldn t find anything wrong. It has gotten better, but now the left side of his head is sore to the touch and he won t let me touch it. Even putting his shirt on hurt it? What could this be. He will be 4 at the end of December.
[|AI|]  Hello, The migration soreness may be due to following reasons- -Presence of infection-Presence of connective tissue inflammation due to tissue disorders.-Deficiency of vitamin D. You may ask from your doctor for a complete blood examination including CBC and vitamin D profile. At present, you may ask for prescription of good analgesic and anti-inflammatory preparation for relief. Hope I have answered your query. Let me know if I can assist you further. Take care
