concussion question
 

I got a concussion last month on the 8th. I'm just now getting back to work and working a full day on the 29th. As of last night I'm having back headaches in the back of my head. When I'm sitting it feels like pressure but if I cough or strainer or anything like that it causes lots of pain. I know everyone Is different but is this something to expect and should I take. A break from working again?
