<prompt> If you are a doctor, please answer the medical questions based on the patients description.My daughter is 12 years old and she got out of the shower last night and her legs were blueishpurple and veins all over her body were highly noticable Bright Colored. The color is still faintly there but it shows up more after a shower. She has not pain or tingling but she did have Chiari Malformation surgery a year ago. Could this be a complication or what is this??  <response>: Hi, By what you say I feel that this could be ambient temperature induced reticular formation on the skin which is physiological and does not require any treatment at all. I do not think this is related to the surgery which has been performed 1 year back. This is medically called status marmots but at the same time to be 100 sure I would suggest that you upload an image. Hope I have answered your query. Let me know if I can assist you further.
