I suffered a concussion 25 days ago hitting the back of my head on a turf surface while playing soccer.

I've been having a bit of sleep trouble the last couple of nights, at least partly due to my mattress caving a little bit and needing to be replaced. I have a new mattress coming in a couple of days but after waking up very early in the morning today, I sat up in bed exhausted and a little bit cranky/frustrated at my inability to sleep.

In my delirious state, I let myself fall backwards onto the bed but held my head up so as not to let it strike the pillow too hard. I made impact with the bed/pillow with the top of my back/bottom of my neck.

I wonder if this could be a problematic type of impact that might impede my recovery. Any thoughts would be appreciated.
