I used to work with chemicals in a Lab with no proper conditions. one day I started to feel like ants in my toes, a few days later - these ants were all over my body. and a while later - my skin all over my body were numb. then the pains started - muscles pains here and there. All my tests were normal including NVC, QST, MRI. All this is more then 3 years. My neuro think that because it was a rapid onset with a very little progression - it might be toxic.

I really want to know what is the origin - for meanwhile it is idiopatic.

Do you have pain all over your body or just in your legs? (I didn'y get it). Do you still work with these chemicals? if not - how long after the onset did you stop working with the chemicals?
