Can Anyone At All Explain Something I Have Had Vertually

can anyone at all explain something I have had vertually since childhood? it started when as a small child - if I was covered with any bedding containing wool I would protest, as it felt like as if the blankets were full of needles: also, any knit-ware with wool (even the tiniest amount) would feel scratchy: the real concern here, is nothing has changed (I'm 63 now) I'm forever cutting out labels, sewing pads and tape on undies since they itch and scratch: and worse of all - relationships have suffered (I'm still single) cause if I am 'caressed' 'touched' etc..I feel like insects are crawling on my skin: causing me to shout "gerroff me" I will obviously die a lonely old lady! what is the problem here??
