Many of us are allergic to dust, fabric, pollen, pets, and a lot more. I have heard of people being allergic to wool. The first allergic reaction could be skin irritation. It can cause itchy rashes. Another popular reaction is nasal congestion. My friend had severe allergy when in contact with wool, she used to sneeze for hours then it would end up in a blocked nose and congestion. It can also cause irritation and redness in your eyes. You can try using some other material like fleece instead of wool. You can undergo an allergy test to discover the allergic factors.
