Yes my nine year old son has been complaining of pain in his hips and most recently his right shoulder. Last week I noticed some lumps coming up on his leg. One on his shin bone and the other just below the knee. Then last night I noticed a lump the size of a golf ball right above his clavicle bone. He has not been sick as in a cold or anything recently. But I have noticed that he is very pale, more tired then usual, has excessive night sweats, and is always itching badly. Should I be concerned?
