so sorry !!! ER often NOT "good" experience, lacking in comfort & care desired & needed after Trauma like you & son went thru. also seem to do poorly for providing for what can't see, like Pain.

most ER don't know how to deal w/ Head Trauma to Dx, appropriately treat, esp. "mild" TBI .--if out for less than 30 min , class as "mild" tho it doesn't feel that way !!!

Specialists--like NeuroSurgeons are not called in except for most severe "obvious" injuries and coma.; rarlely do closed head injury, get more than basic tests--CT Scans, x-rays--which often show nada -at that time.

Did they find anything on any tests??? They wanted you stay --I understand your wanting to leave, esp. when didn't have Your Meds .

I don't know about your condition or meds taken, but wonder if --in this emergency situation--your brand name med could've been substituted -- and generic taken briefly (till you could get yours) -to enable you and your son to remain in Hospital for further evaluation & possible additional treatment??

You presented ER w/ some complexity-- Hx of previous med condition--affecting Brain.
Reporting symptoms of TBI--loss of consciousness, vision & audio disturbances and more... "redflags"

in this situation--were "non-compliant"-- you refused the treatment they offered--to stay & take generic med--
which was NOT what you wanted, or perhasp not even the Best -- but... what they did offer...

I can relate--- when in pain you want Relief,
ER is so stressful you just want OUT--esp. if you're cold, dirty, tired, hungry , upset, & more --as you would be after accident.
but the fact is they wanted you to stay & you refused.. Did you sign form --AMA- that you were leaving Against Medical Advice?? if you did-no biggie--it's way to cover...

But the Symptoms presented and If the pain, muscle spasms are so severe to make you cry--you need something--as you already know---

ALL these are signs that sometings wrong, that could become worse w/out appropriate DX & treatment. Hopefully NOT --but needs to be pursued to know IF something else occured w/ accident, and to get Pain relief.

if you haven't yet--CALL your DR.
state~ EMERGENCY--as it is!

Most DRs can be paged and do return calls, or who ever is on call. Hope they do more than say go to ER ( which often occurs)

Weekends are terrible for accessing help beyond ER. But some of my DR's have either come to ER, or are at least were called by ER for further details & suggestions on how to treat & get more HX.
if you can't connect w/ your DRs ---go to ER--don't have to go to one you were taken, unless selection of Care facilites is limited in your area.
also If you do go to ER or Hospital-take Your MEDS , w/ you. IF don't have exactly what's needed in their pharmacy, often will allow yours. don't need Re-runs.... enough bad experiences already! But if you feel don't want to go to ER , & can tuff out till get appt. w/ own DRs/specialist... get attentention ASAP

--don't wait too long & suffer longer.

You said son wants Med attention & sounds like he also needs to be further evaluted.
Whiplash --commonly occurs and can create types of Brain injury as well as Muscle disorders that are painful & can last long. as well as other types of injury from trauma like this; also PTSD..

Most head injurys (concussions, "mild" TBi) resolve quickly but some do not.
I may not be telling you anything you don't know, as you stated Dr. said another Impact could cause more problems...

You & son have problems Now, that are crying for intervention.
I hope you are able to access attention needed ASAP, and receive most appropriate & Compassionate treatment. some ER are better than others; often just going at another time ( different circumstances, Staff, etc. ) makes for a different experience.

I wish you & son the Best !! and pray you both Heal well & quickly....

Let me know how goes... I don't usually Post here, Mostly at Forum for TBI -Traumatic Brain Injury & Post Concussive syndrome_PCS.
I know & am learaning (hard way) about repeat Head injurys> and frustration of finding "right" Drs & treatment.
Good LLUCK

ps---vestibular problems often occur--may need to go to Neuro-specialists for that "gong" sound . But start w/ whatever DR's/ medical intervention you can access... ASAP .... it may be process, but I'm prayin you & son get what's needed as soon as possible.
