I've got a few questions.

I was recently about 8ft from a massive chemical explosion. I went to hospital by ambulance and was diagnosed with concussion and pcs. I follow up today. This is a workman comp accident. Since the accident I have terrible headaches which get worse everyday. Hearing loss, neck pain and severe nausea. I'm dizzy, can't sleep and have to stay still as possible. I vomit riding in a car. Is this normal?

I feel horrible, I can't sleep at night. Im scared this is going to cost me my job.

How long should I expect to be out of work? I have insurance to cover my pay (work comp, short term/long term disability and accident insurance)

I feel like this has changed my life!
