I have searched online for answers to this question and found this forum. The reason that I am coming here to ask is that my husbands concussion doctor is out of town for a week and a half and it isn't an emergency.

My husband was in a car accident one month ago which resulted in a concussion. He wasn't given a protocol to follow until 8 days after the accident. He had not had any headache or nausea for 2 weeks, just monitoring fatigue and taking breaks. He is not back to work full time. On Friday, he got very nauseous and then his headache pressure got worse throughout the day. He did end up in the er because his doctor made him go but he just got sent home. After 18 hours in bed he seemed back to where he was before.

The question is because he was doing really well and we couldn't identify what would have cause any agitation to his brain but, we both have bad colds and he also had a fever. Is there reason to believe that the coughing and sneezing could have agitated his brain injury?
