Hubby went back to the hospital last night. He still had a headache all day yesterday and wasn't feeling up to snuff. He kept forgetting things like which movies we had watched over the weekend, what day it was, and couldn't really focus or concentrate. The doctor ordered a CAT scan and a neck X-Ray and everything turned out OK. No concussion, but the doctor said hubby probably has post-concussive syndrome. We googled it last night and the symtpoms fit. He should be completely better in a few days. This morning he woke up headache-free, so it seems the doctor was correct. I'm glad he went back and had the scans, and I'm very relieved that nothing serious is wrong.
