I am suffering from itching all over my body, including my scalp, eyes, and inside nasal passages. I m using a humidifier, changed the filter on home heater, and am even taking meds bc my primary suspected it could be anxiety. I do not agree. I have no rashes. My little grandsons were in my yard (in my new home) and after only a few minutes complained that I had itchy grass . Although I don t spend much time outdoors, I was wondering if somehow allergens, weeds, etc. could infiltrate my home and cause this.
