Wearing anything synthetic causes extreme nausea, faintness and beating heart?

I am 67and female. I have always had very dry skin, and at present wearing anything synthetic causes extreme nausea, faintness and beating heart. The symptoms gradually worsen until I remove the offending item(s). The same symptoms occur temporarily if I even touch synthetics fabrics of any kind. A dermatologist recommended Aveena moisturizing cream and prescribed Clobetasone. But the Aveena produced the same symptoms and I had to bathe, flannel and towel it off, and do not like therefore to risk the Clobetasone. The condition has gradually become more extreme over the past couple of months. I cannot even go out, as the synthetic lining all coats have affects me even through the clothes underneath, and feels as if it is burning me. Could I have thin skin? Would extreme dehydration cause it?
