Owen, I slipped and fell hitting my head on tiled cement floor. It didn't seem like a big deal but I was unconscious for 5-10 minutes and have been having headaches, blurry vision, ringing in my ears, feeling very tired/sad/no energy or desire to do much of anything. Have been seeing a neurologist and has me on indomethacin, oxycodone, flexeril, with no help for headaches. Sent for Cat scan and MRI... all negative. Haven't been to work and generally feel very bad. Not sure where to go from here and it has only been a month.
