Hello! My question is in regards to a high vitamin d level in a 3 year old. My son began itching his legs about 6 months ago. We have been struggling to find a cause and have seen several doctors. After ruling out any possible contact dermatitis issues from soap, lotion… As well as getting him allergy tested for food and other allergens we decided to get blood work done. The only thing that came back abnormal was a pretty high d level which was 93. He is otherwise very healthy, energetic, happy, no G.I. Issues and has normal calcium levels which I have read may occur along with high d levels. His skin is perfect i.e. no redness, dryness, bumps except that he itches them to the point of bleeding. The itching seems brought on mostly by heat as well as by foods which contain sugar- processed as well as fruit sugar. I have read that a high d level may cause incidence of allergic skin reactions and skin itchiness in general. He has been off d supplements now for 2 months and has not improved yet. Have you heard of this before? If so, how long does it generally take for symptoms to improve? I suppose my next step is to get his blood drawn again to see if his levels have dropped. I'm very confused and looking for any guidance and experiences. Thank you in advance!

    When you say a level of 93 is this measured as ng/ml or nmol/l?
    How much does he weigh and how much Vitamin D was he taking a day?
    How long was he taking the Vitamin D before the itching thing started?
