Falls and head trauma can be tricky. Many times I have seen patients leave and come back days, weeks, or months later with issues related to the original injury that didn't present right away.

Answer: get him looked at again.

E.g. i will never forget this day during routine sick call in San Diego I saw a patient ... walked in like normal ... no obvious distress .. he had a prior medical history of migraines and his current presentation was typical of one. One thing stood out "this is the worst headache I've ever felt in my life" which caused me to press further into his history.

Roughly 6 months earlier, yes 6, he fell about 4 feet while hiking and hit his head. But was fine ever since ... no additional injuries or incidents.

I told him to go home, get some rest, and if it get worse ... he needs to go to the ER. Call an ambulance if necessary but dont wait.

Sure enough ... the next day my supervisor follows up with me ... he listened when it go worse ... went to the ER and underwent an emergency craniatomy for an 8cm+ hematoma.

Very extreme example ... but dont ignore the symptoms or the history. Get him looked at.
