Its hard to say, does the bruising hurt? And he needs to get checked out, it could be many things that he , or you dont know about.
Hi
Welcome to the MedHelp forum!
The spots could be tiny bruises. Deficiency of Vitamin B12, folic acid, or Vit K could be the cause. They could also be fragile spider veins. The spots could also be petechiae, which are pinpoint-sized red dots under the surface of the skin. They can result from autoimmune disorders, such as lupus or rheumatoid arthritis, bone marrow disorders such as leukemia, inflammation of the veins, as a side effect of certain medications. If along with spots there is itch, then it could be contact dermatitis due to bra material or soap, powder, deo, perfume etc. It could also be herpes, if there is pain. Do discuss this with your doctor and get your son examined. Take care!
