<s>[INST] I have a 2 week old baby girl who has some purple marks on the inside of her right leg. It looks like purple veins or bruising. We went to the doctors and they had gone but now have re-appeared a few hours later....any ideas what this might be? Could it be heat related? [/INST] HiI understand your concerns but don't worry. Such transient discoloration can be due to pressure (diaper/fabric/harness) or heat. So, avoid that if possible. No need for any treatment.Take care </s>
