<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi I have a question about paragard, Wilson disease and gilberts syndrome. I have that I UD and have also been diagnosed with gilberts syndrome, but have been having pain in back and pins and needles down my leg, right now its only in my foot. Had MRI and ex rays that showed nothing wrong with my back. Could it be Wilson s disease or the copper in the IUD effecting me.  <response>: Hi, thanks for posting your concern in the Chat Doctor. Copper containing IUDs are known to exacerbate Wilsons disease or existing Chronic Liver Disease. But, there is no convincing evidence that they cause Wilsons disease. As you have Gilbert Syn Chat Doctor. But, that would not precipitate Wilsons disease too. But, it would be better to switch to some newer IUDs if you have any form of Gilbert syn
