What Causes Headaches,facial Pain And Numbness In Arms And Legs?

For 6 years during the 80s I spent every day at work with my hands soaked in Xylene and Toluene, cleaning silicone.I now have chronic cluster headaches - since 96, neuropathic facial pain and parasthesia, left side, since 96 and severe neurological hypersensitivity and numbness in arms and legs, since 90.I have had multiple MVAs, including crushed neck vertebrae in 89.Could solvent toxicity be cause of some of my neurological problems? Thank you.
