My son is 6 years old and during the last month he said in a couple of times that his \"heart hurt\", \"his heart is going to explode\", and yesterday after his complaint I noted his chest and abdmen vein very dark, almost like a map in his body, should I go to the hospital?
Hi....by what you quote I feel that the skin issue he is having is - Status Marmots. This occurs due to ambient temperature change too. But the darkening of skin I am unable to decide without seeing it. I suggest you to upload photographs of the same on this website, so that I can guide you scientifically. But with the complaints of Heart exploding and associated darkening of skin I suggest you take him to the nearest physician to get him examined. Hope my answer was helpful for you.  I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
