I just need to know if it possible that a medication was taken for 7 years, after stopped, but still have it in system, to have high-sensitivity to it, where anywhere there's traces of it, it still affects me (I have a skin desease and it reacts whenever I around objects that were around this medication - again, I need to mention this was large amounts of dust and boxes of it, and it got cleared away but it seems like, the dust spread everywhere instead.) I have always been ultra-sensitve, the most smallest thing affects me, so I don't doubt this is possible, but I would like some scientific back-up for it. Thank you!!
