I like to get out and be with people, however when my chemical sensitivity is severe, getting a whif of diesel fumes, perfume or cologne, cigarette smoke, incense, candles burning, or some cooking odors can quicky cause muscle ache or a headache. When my chemical sensitivity is severe, I become fearful of what might suddenly trigger a bad reaction. The chemical sensitivy is very extreme at times, but at times not so severe. I am in the process of getting my amalgams replaced.and am more than half way done. i am a single 48 year old man.
