I suffered a concussion about 3 weeks ago, dropped 95 lb weight on my head.  I have been to the ER and my primary care physician and I do have another appointment tomorrow to talk about the fact that I am still in a lot of pain (headaches), dizzy, and nauseous.  The reason I am asking you right now is that today I started having horrible blood rush to the head when I stand up or move too quickly.  I have been doing very little - mostly sitting/ laying to fully recover.  Its so bad that I have to brace on something or I will fall over and my vision goes completely black with stars.... It was so bad this morning that I actually ended up vomiting.  Is this part of the post concussion syndrome?  Is this something i should look further into?
Hi, Thank you for posting your query. It is common to get these symptoms, in a patient with post-concussion syn Chat Doctor. For relief of symptoms, you may take betahistine tablets. If a CT scan of head has not been done so far, please get it done to exclude any internal brain injury. Please get back if you require any additional information. Best wishes,
