I am a 30 yrs old man. got exposed to toxic hydrocarbon fumes when I was burning small amount (~20g) of Aziridine polymer and polyurethane at high temperature (200-500C) [They may release hydrocarbon amines, CO and possible low isocynide]. I got exposed for 30min (on Oct-30th 2012). I didnt have any cough/nasal-drain during the exposure and even after that. I started having frontal headache 2 hrs later and rib pain on the lower right side started 2days later.
Headache is persistent (24x7) and all the time (varies from mild to severe, usually worse in the morning, light during the day and again gets heavier in the evening) since then even ~6weeks after the exposure. Although all blood work (CBC, CMP and thyroid) and imaging (Chest x-ray, abdomen ultrasound, CT of chest, and CT of head) came negative but there is no change in the symptoms even after ~6weeks.I had no health issues in last 8 years.
Any suggestion for any diagnostic test that can reveal the damage (if any) caused due to chemical inhalation and understand the cause of my symptoms, or what else could be wrong w/ me would be heartily appreciated.
