I am a public school bus aid. I was gravely affected by the diesel fuel fumes last Thursday. I have environmental and chemical sensitivity. Mechanic informed me that particular bus has a blow-back fume problem. Meaning the fumes will be pushed into the bus, fill it with CM. Experienced sever headache, achey neck, shoulders, chest pain, calf and knee caps. Since then in the following days still have chest pain, right under arm pain (whick feels like plurosi (s), which I have had. Still experiencing confusion and waves of headaches. Appetite not back to normal. Please, what should I be doing ?
